I have noticed that the SX-1080's are kind of far and few between on Ebay which is probably why Crooner got top dollar. They seem to be more rare than SX-1250s and 80s? They do go for a lot. I was watching 2 of them that this 1 guy had both go for over $400 here recently (they were "near mint" and might have been Crooner's). If the one your looking at is clean and works w/o any noticable glitches, I would try to offer less but $320 is realistic- IMHO anyway. ESPECIALLY if it's in excellent cosmetic cond. Personally, I think, in terms of their "real world" wattage output, that I would MUCH rather have one of them than an SX-1280 or 50- that's just me though.
