Good thoughts Hanse. More money is not always better. The biggest problem for me is I don't really want to run a credit risk just to get two tv's to look at. The other problem is, there are no Optoma dealers near me, so I can't go anywhere and see one of these puppies in action. If I could, I would have by now. Its almost one of those, "If it seems too good to be true, it probably is" type situations because they listed for $5300 new and now a year later you can pick one up for 50% of that. But of course, this week is CEDIA, and I'm sure Optoma is going to announce the new line of the same TVs. All I can think of, is maybe improved optics, cableCARD built in, and possibly adding an HDMI connection and moving up to either HD2+ or HD3. And I can't seem to find a good comparison anywhere that explains the differences. Hell, the newest TVs are already touting HD4 chips and I can't even find a press release on TI's website saying they are producing them!
The other problem I have, is if I window shop at Best Buy, or Conns, or another big box retailer, I know all the TVs are badly calibrated and none of them will let you screw with the settings to get a realistic picture. Even worse, I know more than any of them could dream to know. Plus, they are all easily 500-600 over priced, compared to what you can get one online for, and you can usually talk the online guys into free drop shipping... Its a tough decision.
(Funny story real quick, but I was in a Conns last week shopping for a washer and dryer and actually ended up giving the sales guy a lesson in HD! He was so happy to learn everything I told him about HD and the differences between DLP, DILA, Lcos, plasma, etc, that he gave me the rock bottom price on the washer and dryer and I saved $500!)
