i have one called the "agptek rocker", it has basic rockbox support but a pretty leaky cheap lcd. i like that it has bluetooth, but i don't believe it's supported yet in rockbox. it's available under various other names but i believe it can be had from about 50usd.

it's quite interesting with more modern rockbox supported pmps, rockbox is run as an SDL program stuck into the modified linux firmware. this device is moderately powerful with a 1GHz MIPS ingenic x1000 CPU. fun to tinker with.

fiio has some nice devices (some with RB support, e.g. the M3K), too. but i wish they had bluetooth. i guess it's not cool with audiophiles so intentionally excluded.
