The Sansas are great and have gotten great reviews. (specifically the E200 series) I'm sure there are lots of reviews out there for the M-series. I say start at http://www.anythingbutipod.com, and then here.
Oh... well looks what comes up first!
I want to get an MP3 player and I can't really get the expensive iPod. Is the "SanDisk Sansa M240 1 GB MP3 Player (Silver)"(I got this off amazon) good? It costs a fraction of the same size iPod. I don't NEED a color screen, it would just be a cool thing to have.
