I just picked up some random RCA 4GB MP3 player for ~$50 two months back or so. I had no special needs though. I just wanted an MP player for use in my car. There was one that was very similar (only smaller and with a smaller screen) for almost half the price at $30 but with half the space at 2GB. Just pick anything? It honestly doesn't matter too much, and I can say that knowing it's the truth in this case since you didn't list any needs or so forth.
