This guy did a great job on my 360 Elite back in December of 07. It was a 79FL, so the drive needed a modchip (the 79 Passkey Chip). I knew this guy was a pro, because the 79 Passkey installation required removal of proxy and solder braiding for those very very thin soldering points (if you have no clue what I'm talking about, then google for 79 passkey installation tutorial). The shipping took about 3 days each way (on East Coast), and he only took a weekend to finish the job for me. I've already beaten Assassin's Creed, Halo 3, Mass Effect, and a ton of the other games on the machine, and haven't had any problems on it.
