If anyone is looking to pick up a Model 64 w/4 inch barrel in the square butt configuration you might check Southern Police Equipment Supply in Richmond, Virginia.
They have recently received some more of the Virginia DOC trade ins and the price listed is $329.99 plus shipping if you are getting them sent out.
Just thought I would pass it along since that is one of the better prices I have seen lately. Picked up 2 and can't wait to get them in.
