Just buy what ever you're in the market for. I've heard stories about Jim Christianson (owner of Inchworm) and they have all been great. I've even talked to him on the phone a couple of times and he is a great guy.
Personally, when its drivetrain related, I would never settle for just $89 bucks, Especially when it's
weaker than stock.
That's like someone offering you a G52 when you could buy a R151F for just $89 bucks more.
