Honestly, I think most DVD players have them these days. For that matter, many TVs also have a USB port on the back which supports playback, but that varies a lot more between models.
They do exist. As for deals, I cant help you there, maybe a second hand store
Yeah, no problem. I have 3 of these Samsung BD-J5700 players. Found 2 of them at thrift stores, cheap. At one time, I had a hard drive I just left plugged into it with a bunch of shows and downloaded YouTube videos. It worked great. Now, I just have a PC plugged in and my players are just collecting dust. But if you can find one of these, they work great for playing off USB.
Try your tv if you have one already. My flat screen tv has a USB port, the only issue is it only reads a few levels deep so if the folders or files are nested too deep, they might need to be moved so they are only 1-2 levels deep
