So, I put a post on here a few weeks about about the Model 57 I scored, never been fired for $500. It shot well the other day and had a nice grouping! Well, I am torn, I am meeting with the seller again tomorrow, hopefully to purchase another piece. They are all about the same shape, never been fired or shot very, very little....

Which one do I buy?

Nickel 4" model 19-3 for $400
Model 25-2 for $600
Pre model 25 for $800
Colt 70 series blued for $800

I meet with him in 11.5 hours. Opinions please?
