I just got mine installed by these guys 2 weeks ago, primespeedtuning.com, I called them Thursday, they said bring it in on Saturday and by 4pm I was driving around. I'm very happy with the price and the service.
I also called a couple of other shops that were recommended to me by some of the older members on this forum that responded to my previous clutch thread and they seem to be pointing you in the same direction, which is great (thanks guys/gals), but my only issues were that the earliest I could bring my car in for service was May, 11th and the shops were a solid 1-2hr drive each way.
Also $400 - $500 seems to be the going rate of most shops. One shop quoted me $725 for my clutch install LOL.
Which ever route you decide to take, good luck!
