Having little kids, I'd be looking at something simple and robust.
One little hand on the drawer, bam, and it won't play no more.
(at least I think so)
We had a Denver, it lived through maybe 100 DVD's and then it didn't work. Was tricky from the start.
Then a Philips. just above a year old, and already, - typical and naughty failiure, won't play last 10 minutes of a film. So You watch almost all, and then no chance.
So, me too is looking for a dvd player, and since neither of my former ones were so cheap, I'll settle with a cheap, and have it on a shelf out of children's reach, just in case.
