You didn't say if you already had an ipod... but if you don't, and you're shopping for one, I'm a big fan of buying "last years model." The Apple refurb store usually has some good deals, and they come with the same 1 yr warranty from Apple.
Also remember that "ipod" is the Apple brand name... there are plenty of non-Apple portable digital music players out there. Some of them are very cheap, but they may or may not be easy to use. I'm an ipod fan myself, but there are definitely other options worth considering.
