Im probably going to get reamed for this one but... Does anyone know anything about those cheap double din headunits all over ebay like this one...

7" Double 2 Din 7" CAR IN DASH DVD CD PLAYER STEREO USB: eBay Motors (item 280559872548 end time Nov-07-10 20:34:38 PST)

I really dont want to spend a million dollars on a headunit. All I want is gps, dvd and ipod connection...

I know you usually get what you pay for and thats probably the case here but I just figured id ask to see if anyone has dealt with one of these before..

thanks in advance for any help you can give!
