I've got one of each. Ruizu and AGPTek are both brands to consider for a cheap decent player.
All still work great, I use them quite a bit. No Audials support on any of them, but since they are easily 'fixed' I don't worry about that.
All still have decent battery life. I use a microSD card in each of them, no problems with that.
Yes, the Sansa Clip+ was better. I've never found anything as good. But for the price of these little players I can't complain. Just make sure your books are tagged correctly!!
