Replacement DVD unit

Has anyone replaced the DVD head unit? I just bought an 02 and the dealership is taking forever.
I see some on Evilbay for $50 so I was thinking about getting one of those?

Any suggestions?

If you get an aftermarket get one that DOES NOT have a tray that pops out for the DVD. Get one that the disc just slides into the slot. This way you won't have to find out the hard way when some kid or person busts off or messes up the tray.
