well it depends on what ipod interface you mean.

Pretty much all of the ipod nano clones have the same interface to a regular degree, or if you mean itouch then yea, most of the players that look like the itouch has the interface too.

Of course these players are all cheap and not high quality ones.
Ill see if I can find some players and their sites, but yea at mp4nation youd be able to find all better quality mp4's that have the sorta interface.

Also the plus of mp4nation is that most of their players (i say most but for definite i only know of a few) the upgradable firmware availible allows for the players to display album art.
