Bubby,
another good site is "THE HD GURU.COM"
LCD rear projection is ok, i have a sony 52" LCD RP. quality in HD is good. regular def is poor at best.I also have a 32" Soney Bravia 4. low def is very good and HD is top quality.
tell him not to get caught up in size. Picture quality is what he should be looking at. there are a lot of TVs out there today. tell him to do his research before dropping $1000.00 or more.
you should also be aware that the your cable or satilite provider can not deliver 1080P.
Blue Ray Disk/XBOX/Sony Play Station3 are the only devices that can provide a full 1090p resolution. so unless he is gamer or plans on spending $500.00 on a blue ray player, he should understand the lingo before he buys.
lastly, the price on the sticker is not the real price of the TV, all of the big department stores will try to beat each other.
