I looked at these but in the end I didnt trust em. I ended up buying two seperate units with infinitly more features for less than half that price.
I got a 7inch tft jobbie with the top resolution (2400 x 480) I think that one you posted is 900 x something. Mine has a built in TV tuner too and remote control etc etc, all for £110.
The head unit I got reads every format from CD, CDr, CDWR, DVD, DVD r, Picture discs, MP3 etc etc and can even play MP3s of a DVD so about 4.6GB on one disc (around 1000 songs). It plays all region DVD and switches between PAL and NTSC too. Pre outs for sub etc, cost about £90.
They do make a single unit like that one but its about the same price, the spec is a LOT better though. You still sacrifice a lot of features by having a single unit though.
I'm in America at the moment but in the end I bought it over the web and they are delivering it to my home in the UK to save me carrying it so no reason why you couldn't get one the same way.
I'll pm you the link if you're interested
