Creative MuVo V100. (2 gb.) I used to have a 1gb Sony, but I can't stand their sonicstage software. It pretty much DRMs your music as you load it on so you can't put it back on your computer, although I think theres a workaround these days called GYM(my Sister still has a sony, so I use it for her when she needs to).
I would like to get a hard drive based player, then I could have quite a few albums in the full flac, but I would be so paranoid of dropping it and ruining the drive that I wouldn't take it anywhere with me. These small flash drives take alot more abuse.
