I haven't checked lately, but I'm sure you can still find re-furbished e200 series players on eBay, and other places. I agree it's the best "full-size" player Sandisk has ever put out. Built like the probverbial Sherman tank and has a replaceable battery. Rockbox does indeed work awesomely on them too.
I also like the Clip+, but no album art and the screen is a lttle small, resulting in a lot of scrolling. I can't say I enjoy Rockbox on it as much but I think it's more of the matter of the small screen.
