I bought one at OfficeMax yesterday. The "MadDog Dominator 6 in 1 Dual 8X DVD+-RW" is really a black NEC ND-2500A as mentioned above (above the UPC says MD-8XDVDRW-PM). I haven't had a chance to test it yet, but the cd freaks review sounded okay for my uses.
I was already at OfficeMax to buy two Memorex CD-R 50-Packs [for the price of one](http://www.officemax.com/max/solutions/product/prodBlock.jsp?BV_UseBVCookie=yes&expansionOID=-536907233&prodBlockOID=536933332), and when I saw the MadDog Dominator for $50-ish, I said, hey why not. My linux computer just lost its Plextor PX-W1210A ([died of overuse](http://club.cdfreaks.com/showthread.php?t=99900)), and I needed a replacement. I'm not going to be ripping games; I'm going to be doing system backups.
My only complaint: the OfficeMax [Rebate Center](http://www.maxmyrebates.com) hasn't updated to show the rebate yet. The dates don't match from an identical, older rebate.
I forgot to mention that there's OEM software included: Nero Express 6 and various other Nero stuff. I've been wanting a real copy of Nero for a while, so this was a bonus for me.
