Sansa makes good inexpensive models. Sansa Clips come in 1,2,4, and 8gb models. They are said to have excellent sound and file support and are very small w/FM radio. I'm buying one for the gym. Creative also makes some good smaller players.
I am looking for an inexpensive mp3 player (around $50) to get for my mom. She's not the most technically savvy so it needs to be easy to use, but I'm wary of brands I don't know much about. There are plenty out there, but thought I'd ask for suggestions. She has a PC, and probably doesn't need a ton of memory as she'd be using it for walking mostly. It would be nice to have a radio feature too. Any suggestions would be greatly appreciated!
