there are several mp4 stores that see supported and branded chinese player, ebay is just too much hassle
www.mp4nation.net
www.mp4nation.net/forums
or
www.allpmp.com
are 2 that are trustworthy and that i have bought from
there are others also but i only list sellers i have actually dealt with as the web is a dodgy place at times
basically for you $100 you can get a much better player which will be better made and fully supported with uptaes and fixes, buying unbranded is fine but you do not pay more than $50 ish for one otherwise it s false economy IMO
cheers
