Rockchip players?
 

I've been seeing the term "Rockchip player" in this forum recently, and I get the idea that they are desirable. I don't know anything about them, so could somebody tell me what the advantages of a Rockchip player are?

Rockchip player advantages(I'm comparing rockchip with action chip players, nano clones..) :

Good battery (well, some are not so good, but a lot better than those action chip players battery.)

Plays DivX, a lot better than the crappy AMV format.

They don't have much firmware problems.

Bigger screen than action chipset players.

Better sound than action chipset players.

Faster than action chip players.

More functions than action chip players.

Faster, and filebrowsing works unlike those action players lol.

Thanks. And where's good place to buy these? It looks like PushPlayDigital has a couple. Anybody else?
