Welcome to my dilemma ..I sold my 8700ub and I'm supposed to get the 5020 here but before it I considered the epson 3020 and Mitsubishi hc7900dw dlp.... So far, I decided to stay away from optoma and benq because their warranties suck and I refuse to spend north of 1000 dollars and be covered one year. That's unacceptable to me because I work too hard for my money.
I'd say its a toss up between the 3020 and Mitsubishi 7900. .. Something tells me the Mitsubishi is better than the 8700 in terms of picture quality...however, nobody has given a fair review with pictures on this site. The epson. 3020 is much brighter than our 8700 so don't expect great black colors .however, 3d is amazing on it. Big decision but nothing makes me want to buy until I see shots of the hc7900
