RE: old encore to new prohunter?
Since the Endeaver came out the price of the Pro Hunter model has come down. $892 seems high to me. You should be able to do better than that. However, if you purchase a Pro Hunter or the frame for one you need to have someone with an FFL license to have it shipped to.
The price on the TC made made stainless barrel seems about right. The stainless frame probably goes for around $300.
