I have the E50A10 - was thinking about a 50" Panasonic plasma, but decided to go the ($1500 difference) cheaper route, and got mine for $2400 or so incl. 5 yr warranty. I do see some SDE on occasion, but it doesn't ruin the experience that much and I think the money I saved justified it.

I was initially worried 50" would be too small, but once I actually got the thing in my living room it's gigantic. So, I'm a happy camper. In a few years when I hopefully have a lot more money due to some game people play with plastic rectangles (and a job, that might help) I might spring for one of the 1080p Sony SXRDs...man those look sweet.
