If you are not planning on using data, how about a Pearl? Small form factor, and you can use at least an 8 gig (maybe up to 16 gig?) memory card for Slacker to cache the music via usb. Its light on internal memory, but you won't be using a lot of other programs without a data plan.
That said, I'm not sure if Slacker will work without data? I *think* it has to connect to the servers the first time you use it to verify your account. Not sure about that though...
