Nowhere that I know of. Most of the ones I know of, CZ, Rem and such start arounf $400 or $500. Might take a look at a Savage. Check Brownells and see what they have. What are you looking to build?for around $200.
If you think those are pricey check out Dakota or Big Horn or Surgeon.I know the Remington 700's and Sako's are very good actions, but they aren't cheap
...buy a used rifle as a donor rifle.
