Any ideas? I've seen them all across the board and not sure where it really ought to be.

$150-$175 in 9/10 shape (cosmetic/ mechanical)

Thanks for verifying that, Kent. I had placed it around there. I found someone that has three and 1 50, but felt he was way high.

150 for very good/excellent condition is a really good price. I'm always on the look out for more 51mgs and have seen them go everywhere from 225 for BNIB to 135 for well-used, well-cared for (7/10 cosmetic, 9/10 mechanical).

This is about exactly the going rate on Ebay. 200+ for NIB.
