is your 2k budget for projector only, or for projector + screen + mount + cables, or the whole thing including speakers?
2k for projector alone is doable. but with screen, mount and cables is gonna be a stretch and require some compromises.
i'm honestly not sure getting the whole thing, including speakers for under 2k will be worth it. you'd have to settle for very low quality across the board.
also, what have you viewed already? are you sensitive to rainbow effect with DLP's?
i'm going to infer that you want pretty much everything for 2k. so based on that, i'm going to say you're looking at either a diy fixed screen, or a painted wall. either way, still factor in 100-400bux for 'screen' painting, masking, or fabricating.
then budget 100bux for cabling and mounts. again assuming we go on the cheap side with monoprice type stuff (not that there's anything wrong with that)
that leaves you with about 1500-1800 to play with for the projector. now there's plenty of good options in that range, but to be perfectly honest, having just gone through this, there's a lot to be be gained by spending a bit more. I went in with the hope that I could find something good enough in the 1500 or under range. the 3020 was one that had my attention because I remembered seeing it for about 1200 on boxing day. to try and make a long story short, I quickly moved from the 3020, to the 5020, and from the 5020 I was just a small step away from the jvc x35 that I finally ended up with. for me, that seemed like the best point to settle, any significant upgrade required a huge increase in price(not to say there weren't other competitors providing similar quality for similar money, like the sony HW50 for example).
anyway, my point is, it might be worth it to reassess your goals and funds. if you can up the budget to 3k, you can get nearly no-compromises movie performance. at your current budget I think you're still dealing with quantity over quality.

I think he did a great job of pointing out the projectors worth looking at at several different price points.
