What is your suggestion on a budget MP3/MP4 Player

am looking for a different MP3/MP4 player.

I own 2 separate China MP3/MP4 players and eventhough they are separate models both have the same issue. When powered on they display either a white or yellow screen. The content is still accessable via a computer, but their operating system seems to have become corrupt. Funny thing is; when one went I figured no problem I still have the other one unitl I powered it up and it has the same issue. Strange that both would have the same issue at the same time??

At any rate...
What would your suggestion be for a budget based MP3/MP4 player?
Which one do you use and what are your likes/dislikes?

I have a sony walkman that I bought last year. It has a decent sized screen and is very clear. Works wonderfully for music and came with good headphones. I think the 8 gig model was 70 bucks. I have an Iphone but prefer the walkman for music.

We bought two cheap Samsung mp3 players about three years ago. My daughter's is still working but the buttons began sticking on mine during cold weather. I use it in my car every day. It doesn't hold a charge very long so I use an AC adaptor. We definately got our $20 worth. They still list for under $20 at http://www.amazon.com/Music-Video-Radio-Media-Player/dp/B005P5E0C4/ref=sr_1_2?ie=UTF8&qid=1363208302&sr=8-2&keywords=mp3 player samsung
