I'm not a big fan of their work. About 3 years ago, my previous car (the infamous "Lemon Drop") went into their shop for a relatively simple motor, rearend, and transmission swap. The donor car was sitting 20 feet away, so it wasn't a question of "waiting on parts". It took them almost 4 MONTHS to complete the work.
To make things worse, the car didn't have enough balls to pull on a Taurus (seriously...my dad's Taurus pulled away from my car under full acceleration). Took it to Race Related where they sorted out the numerous problems AND rebuilt Ramsey's transmission rebuild (which Ramsey's would not warranty). A week later all my problems were fixed and my car ran like a raped ape.
Denis is a great guy, really knows his shit and is really helpful for sourcing parts...but being a nice guy doesn't makeup the fact they took entirely too long to complete half-assed work on my car. Maybe he has changed in the last 3 years, or maybe he hasn't. Either way, there is no way I could ever go back.
