If you want a pretty basic TV, I know there is a 25" Sansui (yep, that's right, Sansui) at BB for $180 or so, I have heard very good things about it, and it has nice features (audio/video controls etc... more then the average set that price)
AFA best brands, IMO Sony and Toshiba are the best, Sony makes real nice TV's and Toshiba is a close runner up wither their bigger flat-screens and plasmas
I would stay away from Apex, or another cheap brand like that.
I have been wanting to get a new TV ( used 36" Sony w/ S-vdeo or compoent input, maybe 5 years old, since you can get one for like $200 or so) as my TV is a 25" Sanyo, plain jane, I mean it has like NO features, mono, although I use my HT system, so that dosn't matter, basic video controls, and only 1 RF input, not even RCA jacks! but I am actually quite surprised by the picture quality of it. I have had it around 5 years now? and only problem with it, none of the front panel buttons work (ok, the menu does if you push it a certin way) but that was becuase a few years back when I was moving the little TV-cart I had it on, the TV fell off of it, hit the floor and the side actually split (where the 2 pieces come together) and I just never bother trying to fix it as the remote works fine.
But if you want a quality TV for cheap, check out a Sony that is 3-5 years old, it should be pretty cheap, and, IMO Sony has the best picture of all the brands.
