$210 is a great price for a tight, functional 64 even if they are holster buffed, etc. If what I'm seeing at gun shows is any representation, they are all showing at least a decade of holster carry and use, but these are duty guns, not safe queens. I think Brinks used DAO 64's, but I'm guessing a large security or armored car company just traded in a whole lot of 10's and 64's.
From what I have read, gun makers will buy a LE agency or security companies old guns, for example, hypothetically........S&W sells Loomis-Fargo 10,000 .40 M&P's, for $300 a unit, plus a spare parts contract and armorer training, and Loomis agrees to upgrade their guns with S&W every 7 years.......in addition, S&W will buy back all of Loomis' duty guns, thousands of 10' and 64's,many of which have been in service since the 1980's...... for almost nothing per each gun, maybe $40 a gun. Then S&W will sell the used duty guns to a distributor for like $80-100 each. This is why we are seeing these for $200-210 each.
You won't find 65's for this price, although there's another dealer who has (had?) a bunch of Austrian Customs trade in 65's for about $300 or so.
Overall, I say get them now.......it won't be long before we stop seeing large quantities of trade-in S&W revolvers. The LE agencies went to autoloaders years ago, now the security companies are getting rid of the wheelguns. I think in 5 years we will all be saying "Man I remember those $200 S&W 10's and 64's!"
The last I saw prices like these, was about 10 years ago I saw a table full of holster beat Model 10 4" HB's (don't remember what - number) mixed in with Taurus 82's and they were marked "S-W Taurus .38 any $150" and people were gobbling those up.......
