I would not pay $450 for a Model 10. I know that's what would be asked by sellers, but I would not pay it. Anyone who thinks that's a good deal is welcome to bag it, of course.
BTW- I am not the only cheapskate. A few months ago I offered a 2" M&P (early post-war gun) to a fellow at $325 (even came with the letter, a $50 value) and he couldn't turn it down fast enough.
To be fair, gun prices in general are through the roof. I joke to my wife that we are millionaires if I could bring myself to sell everything.
