As part of my job I have done a major evaluation of all SINGLE chip DLP's...I have to design a planetarium using a cluster of 13 of them. Just thought you guys would want to know that the best I came across was the Projection Design F1. It is SXGA and nearly 2500 Lumens... I don't work for PD and normally use the Barco R6's and Galaxy's but this thing is brilliant and all for £5k! You could have a cracking 2 channel home cinema with these things.
