I third that notion!
I too ordered the NU DW163 from Newegg - $60 delivered because I purchased on the day it was the "deal of the day" - $55, it's $58 now but the shipping is cheaper (go figure)....
Anyway, the NU is a 1620 - without a doubt. The package comes with Sonic and WinDVD (the WinDVD creator is actually usable, though you really want the free DVDShrink for any drive you own). Sonic's cutter works, but if you have a recent Nero or NTI you have more options.
The NU doesn't supply an IDE cable, and you do need an 80 pin.
