i'm using the PD70X(see mwz post above for the link), and couldn't be more happy. 40GB hard drive, 8MB cache,very quick transfers @ 16MB/s, it's built well, plus i can dump my xd card from my camera onto it as well. i bought mine last month for $200 shipped & it arrived within a day or two. it came with the car charger, wall charger, plus 4xAA NiMH 2500AH.
