I and many others use a Foxwell scanner (NT710 in my case), but I also use Bimmerlink in parallel and I even have my hands in ISTA (which is a project, don't ask, but if you can figure your way into it it is definitely an eye-opener for a thing or two).
I have also recently caught a mention in another MINI forum that Autophix is not a bad option, usually at a lower price point (though by how much I don't know) on Amazon. And then there is the Schwaben, already mentioned above.
