Picked it up on ebay, slightly used.
Some ebay vendors are selling "new in box" units, where I believe you can fill in the original warranty card. AKAI is pretty good about that stuff, so I'm told. I never had any experience or need, though.
Ebay price was $800 - $1000 last time I looked. I ended up grabbing a "buy it now" package with a couple of snakes and a case, so I paid a small premium. Watch for the upgraded units - 20 - 40G hard drives. They'll have updated software as well. The burners are packages that might have a used casing and a new set of innards, available from a consistent ebay vendor who pops up a new listing any time there's a DPS16 for sale so you find it in a search. Good stuff for the price.
The only thing I don't like so far is that the fan has a little whine - about the same or a bit quieter than my computer. It seems that mic positioning can overcome it.
