I have a SharpVision XV-710P that I use nearly every day. The LCD panels are dirty, the picture is pretty dim, and the chickenwire effect is pretty horrific. Trouble is, it's an old projector, so that must have been what it was like from new, pretty much (except for the dirt, and it was poss. a bit brighter!)... I'm thinking of getting a Panny PTAE-100E, but before I do, I'd like to know how much I could flog the Sharp projector for... I'd chuck in an old 8 foot glassbead screen (the beads are coming off in a few places, so makes the picture worse!)... Any ideas (also, any opinions on the Panny)?
