The type of MP3 player you want is entirely based off what you want from it, and what you intend to use it for. Think on what kind of MP3 player has the most available functions that fit
your needs. We cannot rightly give recommendations for a bulky wide-screen MP3 player if you would also like to use it for endurance running.
That said, I myself have been wanting to buy a 30GB Creative Zen Vision: M for a year or so now. It has great reviews(Won CES Best in Show of 2006), many useful functions(such as radio tuner, recording function, HIGH-RESOLUTION screen, etc.) and would fit my lifestyle perfectly. It is also a most intelligent and reasonable buy for the price.
You can find its list as price at anywhere between $180-230 depending on the color you want, the seller, the rebates, the day of the week... It really shifts, but then again, you can buy it at a bargain that way.
Here is the list price as of this moment on pricerunner.com:
