Anyone have any eperience with these? I want a cheap DVD player/monitor for my son in my car, but I don't want something that's going to crap out in a few weeks. Sonic has what appears to be a decent one for $150.

I wouldnt do it. I had a roommate that went cheap on his screen and within in a couple of months features just randomly stopped working. Couldnt play cds then dvds then the screen would randomly turn off. he could only play music through the memory stick card insert. Then finally the screen broke and he had to get a deck instead. A wasted $200
