Hi,
A lot seems to depend on the area...
For example, in my neighborhood, "street price" for new guns usually runs about 75%-80% of MSRP, and a "good" used piece will generally have a price tag asking about 50% of MSRP (dealer price: private parties are all over the board.)
Don't know what current price for the SRH is, but my regular RH fit the model above, as have at least a handful of other used guns friends have bought so you can plug your own numbers into the calculator.
We don't see as many "low" prices here in my part of SoCal as some of you guys can find in less restrictive markets...
