The reviews there at Projector Central cover several models and makes. DLP & LCD.
What always makes picking out a 'best' whatever, is my fear I'll get less than or outright screwed. Given your current level of video and these offers being reviewed by PC... I don't believe you'll make a bad choice.... which ever way you go. I think all of them are substantial steps up from your now situation.
Get what you can justify buying and perhaps add a better screen. then, you will have made improvements across the board.
Check for service outlets closest to you so that's out of the way, and give which ever one you want most a call to their support dept and ask a few questions so you can decide better or be more comfortable with your pick... you'll have it for a while, might as well find out what sort of people you're getting involved with, huh?
Support has made my mind up for me more than once.... all else being about the same.
