I own a few DVD players and I've returned a few. The one I have been happiest with is my Toshiba SD3109 which has been the primary one I have used for about the last year and a half. One of my friends returned both a JVC and a Pioneer before settling with on a Toshiba (I do not remember the model, not the same as mine.) My Apex DVD player which I loaned to my girlfriend, I have had to clean a few times and has been used about 1/3 as much as my SD3109. I have not had to do any maintenance on my SD3109. I have had it lock up on me two or three times over the year and a half, but I can always stop it and restart right where I was. My only complain with it is if I turn the power off it does not remember the current place in the movie like some DVD players do.
I have not looked over Toshiba's current DVD products, but I would recommend them based on my experience and the experience of my friends that own one.
