A retrofit should only cost $350-400 on average if you do the work. Hidppanet.com is a good source for parts. Rx330 projectors are cheap and almost as good as tsx's when coupled with a different lense. Not to mention the output and cutoff far surpasses the jspec's. Graphx, if you're serious about the best solution and are willing to spend $600 for a complete retrofit, pm me - I know someone who does excellent work.
