Just throwing out random numbers, with full repairs and a DPA warranty, you can get probably the $2500 you were asking. Without, I (personally) wouldn't pay more than $500 for them. Fine, the buyer could get DPA to do the repair themselves for $1300, making the total worth $1800, but I've done the YS rodeo way, way too many times to not chop a substantial % off the price for the risk.
That said, it's your sale, do what you want, and I'm not in the market, just offering an opinion.
