Mate I just got 60% of my car resprayed at JAM Body Service and I highly recommend them. They're in Nishinomiya in Hyogo though, so not much use to you I guess. Here are a few pics:
Everything bar the roof, bonnet, front guards and front/rear bumper were resprayed. There was quite a bit of rust around the rear wheelarches and on the passenger side rear "c" pillar, but that wasn't a problem for JAM... I let the result speak for itself:
I was gobsmacked at their quality. They went over and above my expectation, even respraying the rear taillight surrounds free of charge. Now the scary part... it cost me 230,000 yen! Yes, I thought about it, and in the end decided it was worth it beecause the mechanicals of the car are actually quite good, beating Evo_Lee's Lancer Evo 5 up to 120km/h on standard boost...
I think just from the "experience" point of view, you should get your car resprayed in Japan at a place thats got a good reputation. The good Japanese body repairers are just so thorough with their work, you'll be satisfied for sure.
