I have 2 Optima projectors. One is a HD20 (1080p) and the other is a HD66 (720p). I prefer the HD66 because it's much brighter. To my old eyes, there's not much difference between 1080p and 720p unless you're looking hard for it.
I bought the second Optima because they fixed the first one 6 months out of warranty. I'm happy with both of them.
i reallllly want projector but every time i am discouraged.. maybe will buy the 400$ on in thread but the hd66 looks like after a year and half it will have pixel problems from what all the newegg reviews say. Maybe if you take it apart around 6 months and re apply thermal paste and beef up the fans it will be good? / shrug im not doing that will just wait (checked newegg reviews many say same thing after 1 year mark>>)
