Buy LED, LCD or Plasma

Unsound,

Front projector would be great except I read they are not good to run continually and this is the main TV.

With few exceptions, front projector screens don't do well with light on them and the center of my living room has a skylight that's about 8 X 17 feet.

At night you don't know it's there but probably a problem for front projector in daylight and if my wife is home a TV will be on.

PJ isn't for you then. There are some ingenious movable mounts that might deal with the height/placement issue. Here's a good guide for choosing appropriate size for distance: http://myhometheater.homestead.com/viewingdistancecalculator.html
Please note the guide is based on 1080i, with 1080p you can actually go a bit bigger.
As a value driven consumer, if I were buying a set other than a PJ today, this is what I would get: http://reviews.cnet.com/flat-panel-tvs/panasonic-tc-p65s1/4014-6482_7-33490537.html?tag=contentMain;compare

There are better sets, but I don't think there are much better values for a close to appropriate sized set. The current BB price is a good as I've seen yet.

Good luck!

Don't know what happened to the link. Let me try again:

My choice is one of the Panasonic Plasmas, the second line from the top is the best deal. Only issue is the Panasonic may not stream movies directly from Netflix. You can stream other companies directly or from a streaming DVD player or Roku

Whatever you get they will be subject to tweaking just like your audio. We have 2 Panasonic Plasmas and I am using line conditioners and good HDMI with both , it made a difference. I just got a better power cord for the living room set, not easy as they are recessed and none of my audio cords worked. I found that one of the smaller Oyaide cords will fit. The picture is now amazing when they broadcast good signal. Programs vary all over the place from amazing to yuck!
