Portable OGG Players

Why is it so hard to find a decent portable MP3/OGG player at an affordable price? I want something that plays both MP3 and OGG as I have a combination of both ripped on my system. If I had the choice I'd have EVRYTHING in OGG format, but sadly it's not that simple for downloaded music most of the time. I want something with a reasonable amount of storage (say, 10-20gig) that does OGG and MP3 and that's all. Providing it does that for a sensible price I will be happy, but it's impossible to find anything: They're all ridiculously expensive, shit, or ridiculously expensive shit.
