I can't recomend the Epson highly enough.
I wanted to get into the projector scene and thought I'd need to spend over 1,000 to get a reasonable picture, the panasonic 500 or 700 I was looking at.
But I stumbled on a thread here, and everyone spoke highly of it, found it for 500 with a 5ft screen and I'm blown away. It was way above my expectations.
Yes, you can see the imperfections, chicken wire etc if you really look for it, but I certainly don't.
And a 5ft screen, equates to about a 72inch diagonal screen which you simply can't get in the plasma world. At this size the projector is well capable, and probably up to a 6ft but I wouldn't go much bigger.
A massive winner for me, plus it was (maybe still is) in the homecinema choice top five under 4k.
