i would go with one of those from tinydeal, though i can not vouch for quality, ut they will be no worse than those omega ones
at least these ones at tinydeal use the new rockchip rk2706 which means better audio and better vide support, no more restrictions on mp2
good luck
BTW
meizu SL - got one myself, great player, i also truly reccomed you get the mDock, best thing i ever bought, use it every day - excellent
