I can't make any guarantees, but you might want to hold off for about a month or two. Emotiva has put all thier amps on sale around Thanksgiving the last two years in a row. The sale price is usually $699 + $25 shipping and you'd have a brand new amp for about what the used ones will cost you unless the sellers come down on their prices. From what I've seen in the last year, the XPA-5's usually go for $600-$650 + shipping. Calling Emotiva and asking about B-stock may be worth looking into as well. A final thought to make the decision more complicated is the sale price on the UPA-5 ($399 and free shipping). Don't know if it will be enough for your Axioms or not.
