Anyone ever sell anything to dvwarehouse.com?

I am considering selling my old Mac to dvwarehouse.com and was curious if anyone has worked with them before for a purchase or a sale? They seemed to have provided me a fair quote.

Located in Los Angeles, CA. Any news on them would be great.

 

PowerMac G5 Dual 2.0 with 4.5 GB Ram and 160 HD it is the AGP version with 8 slots for ram and the Nvidia 5200 card.

 

I have recieved several quotes:
dvwarehouse $1200
macofalltrades $1000
powermax $1000

These offers all seem better than the latest completed ebay sales on similar spec'd machines - so it is a nice consideration and no ebay fees or gotcha's, but since I have never done any business with any of these places I am apprehensive and ready to jump at the same time...
