So I was thinking about buy the MSD Ignition Coil, but is it worth the money? Has anyone had problems with is?

 

No gain..ZERO, ZILCH...stock is good EXCEPT for the terminals which are nickle plated iron...and corrode...so keep an eye on them..dielectric grease will keep them clean...when it gets bad enough...many options to replace it..include the msd, stock or clones...made my choice based on cost and the brass terminals on some units....
Heck some are convinced it will magicly fry you ecu...just cause summit racing/your local big box auto parts store sells them as opposed to a vendor....
