i think you should be able to get a sandisk sansa+ player for that price. i like the tactile feel and use of those buttons which we can press for playback without looking at the player, the tiny PMP tucked away inside your pocket or shirt, hung from a lanyard. a rugged multi-use all-weather player as well and good for use during hiking/cycling etc activities. i have a rockboxed one which i am not using much now but still reticent to sell it off, as before this i had another one which i had sold off & then felt guilty & need for it again, so had then purchased my current one.
some other good options would be the flash PMPs from sony and transcend, both which i've used in the past.
good luck.
