Stay away from anything with just one cluster of inputs -- one composite, one S-video, one pair of audio inputs, one video choice on the remote. You have to unplug the DVD player completely if you want to use the VCR.
Try to get a set with a real 16:9 mode.
If you can find a "NTSC to VGA converter" and don't need to both use the computer and watch TV at the same time, you can use the computer monitor as a TV and the picture is sharper than a regular TV twice the size. Less weight and bulk to carry around between academic years. If you can find a DVDO iScan reasonably priced, even the earliest model is a superb NTSC to VGA converter and you don't have to open up the computer to install it.
