It depends on how much music you want to download and whether having a screen is important to you.
Check out apple.com to see what's available. The new Nano is around $150 and features a screen and compact clip-on size.
I have a Shuffle 2G that I paid $45 for. No screen and holds about 180 songs, clips on anywhere.
You can purchase these and others just about anywhere - WalMart, Target, Best Buy, etc.

"A bicycle ride is a flight from sadness." — James E. Starrs, The Literary Cyclist
"We run, not because we think it is doing us good, but because we enjoy it and cannot help ourselves...The more restricted our society and work become, the more necessary it will be to find some outlet for this craving for freedom."
-Sir Roger Bannister, first runner to run a sub-4 minute mile
