Magnavox DVD Player, MWD200G
Great little DVD player--the cheapest you'll find!
When I was looking for a basic, inexpensive DVD player to use for exercise videos in my workout room, this is the product I bought.  I have been using it for a year now, and I've been extremely satisfied with its performance.  I have NEVER had a problem with freezing, skipping, or any other playback issues, even with DVD-R and other DVDs known to have performance issues.  Sure, the unit doesn't have any advanced programming or other special features, but it's simple, easy-to-use, and reliable; for the price, you won't find anything better.
