I have been watching auction sites and listings for 610's, so I have a good idea of what the current going prices are for the 610's. I would like to know what others opinions are here as far as whether it would be worth buying at these prices or waiting. Do you think prices will come back down or what do you think the odds are of S&W doing another run of the 610? I did a search for more info on the 610's but couldn't find anything that described what the major differences are between the 610, 610-1, and 610-3. Can anyone explain those? I am wanting to purchase a 6.5" or 5" and currently have the opportunity to purchase a 6.5" 610-2 BNIB for $1250. I don't know a whole lot about the revolvers, but want to get one to complete my 10mm collection.
