my personal experience
had 4 2nd clones, 2 fake memory ones, 2 ok all 4 dead, battery really bad, batteries die even when player turned off (known defect on actions player), navigtion appalling, no artists or music sorting no album art, basically these do not work the same way as an iod, just to be clear
byt yeah, tinydeal are the cheapest, also look at
www.dealextreme.com
and
www.focalprice.com
they will player music but battery is seriously poor, best i ever got was 6 hours from all 4 of mine, as you can see i am not a fan of these
also there are some new nano 4th gen clones that have similar "features" to the new nano, rotate display, shake to shuffle
try
www.digitalkingz.com as they have these new supposedly 1:1 copies of the new 4th gen player

BTW the 2nd gen clones are bigger than ipod so you cant use any of the accessories
