I would buy the least expensive Husqvarna 640 with a large ring FN-made action that hadn't been d&t for a side mount from Simpsons, LTD, in Galesburg, IL.
I would would rather build on a 70 year old Husqvarna 640 than on a new Zastava.
I have multiple rifles built on both actions, with the Zastava's being marked Interarms Mark X and Remington 798, along with another dozen built on military Mauser actions that were made in Austria, Belgium, Mexico, Germany, and Sweden.
If you're interested in a military action, I've got a Steyr-made Columbian 1929 action that I was going to build as a 257 Roberts, but haven't and probably won't at this point in time. It is a straight military action, no modifications.
EDIT: $170 shipped and insured to your FFL.
