Hello, I have a voucher to replace my Optoma EP719 (DLP / native XGA 1024x768 / 2500:1 contrast / 2000 Lumens / 3000-4000 hours) Usage is a mix of professional & home cinema and I was quite pleased with the EP719. I was thinking of getting one of the following as a replacement: 1. Optoma EP739 (DLP / native XGA 1024x768 / 2500:1 contrast / 2000 Lumens / 3000-5000 hours) 2. Hitachi PJ-TX200 (Tri-LCD / native 1280x768 / 7000:1 contrast / 1200 Lumens / ? hours) I'm not too fussed about HDTV, but am more worried about lamp life and the fact that I now have a new laptop with 1200x800 screen resolution. Which one would you recommend, or are there any other good ones out there in the same price range? Also, is there a big difference between DLP and LCD technology? Many thanks David.
