Im replacing my stereo and would like to get a double din dvd unit if possible, but dont wana spend hundreds.

I have found the unit below for around

£200 on ebay, but are beat products any good? A few specialist audio shops sell it so im guessing it should be better than the cheap chinese stuff you get on ebay?

If anyone has any other suggestions of dvd headunits around

£200 let me know, if not, a single din cd player it is!
