I'd check Audiogon - watch the classifieds and/or post a "want to buy" listing. There's also a section of Home Theater Forum for Hardware sale/trade that might be useful. A B-stock unit from Outlaw is $739 (compared to $799 for a new one), and I think they've been holding their value pretty well in the used market. The going rate seems to be around $600. The five year warranty is transferrable on used units, but as OilCan points out a B-stock will come with the full five years.
