When I really started looking, I couldn't believe the crappy signals they had going to so many of the otherwise decent looking TVs. One place had the local cable piped in, but was using composite to send to a distrubution amp, and then using component from that to all the TV's. It took me an hour to get the owner of the place to swap the cables so it would have component all the way, and it made a huge difference, of course. Even he admitted it, after telling me several times it wouldn't. Other places were almost as bad, some had no distibution amps and the signal was too weak, etc.
Most places wouldn't do anything at all, and got upset when I started cranking the color level back to a sane level. I basically looked around until I saw sets I was seriously considering getting a decent signal, and then looking for the next on on my list at another place until I narrowed it down to two, then went and saw those two side by side with an over the air antenna hooked up to each and I spent a long time playing with them before deciding on the Sharp I did eventually buy. If the obnoxious saleswoman had left me alone, I would have bought it from her, but she kept bugging me. Nobody was in the store, I wasn't doing anything she needed to watch me do, and besides, she knows me slightly. She kept asking me what I was trying to do, and even though I explained it to her again and again, she didn't get it. Well, I didn't get "it" from her either. I made my decision though on the Sharp, and when Sears had it for the same price as BB's and CC, I got it there, no interest for 18 months!
