I got a Pioneer from Best Buy. Reliezed I need one with AV jacks so it could serve double-duty as a DVD player and monitor for my camcorder. It's a pretty cool unit, swiveling screen, plays jpgs and mpgs, DVD-Rs the whole shebang. Was only 130 bucks, and I got the extended warrenty.
What size screen is the Pioneer, Andrew? (I don't see a Pioneer model on their site, and the local store has a very poor portable DVD player selection.)
After looking around a bit, I bought an 8-inch Polaroid from Circuit City:
Have only had it about a week. I needed something which could handle my DVD-RWs as well as -Rs (lots of models don't seem compatible with -RWs). Plus, I really prefer this black casing to the silver. I considered going for a 9- or 10-inch screen, but after lugging around this 8-inch, I think bigger wouldn't quite be "portable" enough for me. (I'm not using it as a car accessory, but for other uses.)
*edit* Just found out this player can supposedly play other regions as well. Will have to try when I get home. I popped in a R3 and it wouldn't play, but I'll try the "code" to change to all-region.
