I'd have to say at LEAST $350 - $400, depending on condition, to someone looking for a correct scope and mount set-up for a specific type rifle, NA Cowboys Companion, Polytech Hunter, etc. I paid $250 about 8 years ago and haven't seen that many since. The downside is that there are other mounts that can replace the T89 base, using the same holes, at a fraction of the cost. With mine I took the 2.8 RedStar off and replaced it with a Leapers fixed 4X to save from any mishap from usage. PAX
