I may be too late to help, but a couple of months ago I bought an SR20 Trophy (like the one you describe, but with octagon barrel, quarter rib, and sights) for $1,500 in the same condition. Put a close-out Zeiss Conquest 3-9x40 in Talley QD rings on it and have right at $2,000 in it. I think that would be a fair price, but $2,300 isn't bad.
