1. How do i select the best oil catch can for my needs? I don't want anything too expensive not something cheap. So what should the best oil catch can be?
2. Where is the best place in the engine bay to install it and how is that done?

The ECS one is the best I have seen. The point of a catch can is to get the oil to condense out of the air stream and collect in the bottom of the can. ECS are the only ones who specifically say theirs is baffled and give a diagram of how it works.
BSH takes their catch cans seriously. Externally all cans are welded together to avoid the all too common leaking issues bolt together setups have. Internally better than the competition by incorporating mesh baffling to slow down oil vapors so they cool and condense inside the can instead of your charge piping/engine. All connections are made with push lock fittings and hose to limit the use of hose clamps that would otherwise clutter up the bay. Integrated drain fittings into the base of the catch can makes maintenance a breeze.
All of the BSH catch can systems are designed to be completely reversible and mate up with all factory pcv connections utilizing vehicle specific billet connectors. Kit ships complete with a laser cut stainless steel bracket that will for direct mounting to an easy to access bolt in the engine compartment.
Filter out the performance robbing oil mist in your crankcase vent system. This oil mist creates an oil film in critical places throughout the engine -- such as the intercooler -- where clean surfaces are critical to maximized heat transfer and on your MAF sensor (Mass Air Flow) where the film will cause the sensor to send a false signal to your ECU killing performance.

I just ended up buying the cheapest ebay oil catch can. With enough length of tubing I don't see it being much less effective than these more expensive ones. May be a bit harder to fit since it's generic tho.
Many will look down on you for that but here is something to consider if going the cheap way. Many of the ebay ones have nothing in the can but air. this seems to at least help make them functional at a low investment cost.

Update: I would not recommend the M7 catch can. It has made a slight difference. However it is not baffled. I'm sure more oil would be stored in there if it caught it better.

Hi, do you know what diameter the ports on the catch can should be? There are a variety of port sizes available on ebay.
Dumb question:
What's the purpose of an oil catch can?
Is this only for Cooper S or for base Cooper as well?
It's to "catch" the excess oil vapor that gets past the PCV and sucked into the intake and foul the intake valves.
The catch can should separate the oil particulates so they settle in the can and not go into the intake.
I would assume that both S and non-s may have the issue...not sure.
So, I really like the hose adapters you've got here. I know this picture is somewhat old, but I'm wondering where I find adapters like that. I have a 2011 MCS with the N18 engine. I plan to put my catch can right where it is in this picture. I'm reluctant to cut the PCV hose until I know I've got some adapters that will connect the output of the PCV valve hose to the input of the can, and then the output of the can to the input to just before the turbo. Any pointers greatly appreciated!!
The M7 catch can from ECS Tuning comes with all of the fittings as you see in that picture. Super easy install and the mounting location seems to be made for that!
Also, it's not baffled so I put some steel wool in it to be more effective.

Honestly, If you are looking for a clean install id look at BSH... thet come with machined adapters that plug n' play directly into the PCV ports etc... about as clean as an install there gets....
i bought 2 cans and all the required fittings & hoses for less than a single BSH or M7 can.
*time to hurt feelings: I know everyone has a real hard-on for OCC's. Truth is .. you dont need one. Listen carefully here -> OCC's do NOT stop oil buildup on your valves. DO NOT. They do NOT prevent super knock, or oil vapor into the combustion chamber either. What they will do quite well -> prevent or help with oil contamination from keeping out unwanted condensate and water vapor. Thats it! Now.. do you need a can thats been flow benched and costs 200$ ..? Hell to **** no you dont. Its all a gimmic and while a lighter wallet may make you feel good, it sure didnt accomplish anything else. Overall its the hot temp your engine is reaching that is causing the majority of the issue & oil vapor. Get your ECU flashed and it will run 30-40f cooler... all of this oil vaping issue gets resolved and a can isnt needed at all. Matter of fact - mine havent filled with ANYTHING since the flash and resetting thermostat temp to ~175f instead of the OEM ~230f
"But butbut" they'll say.. "my can blahblahblah" Do you get a milkshake in your can?! Sure you do! because water naturally condensates in the empty surface of the can when your engine/oil cools down (like on the outside of your soda or inside of your windows...moisture builds up). Keeping this crap out of oil keeps it healthy longer. More than 90% of what ANY OCC fills up with is water.. not oil... So, I ask - whats all your fancy baffle science you paid for? A = nothing at all.

So what is ECU flashing?
what I heard was you had to empty oil from can when it filled, so it has worked for some people.
May need be proper installation to work or if anyone has experience of collecting oil?
