As far as I know the TC Encore is no longer made. You can find TC Encore frames on many auction sites. There is a company called SSK making frames and barrels . There are a few specialty barrel makers besides SSK making quality products for the Encore.
I may be biased since we own three Encore rifles plus a slew of barrels. I am partial to the MGM barrels and Bullberry barrels. I get parts from Mike Bellm. Mike and his son sell TC parts as well as barrels. Mike is the guru of Encore actions.
If there is one thing I would watch out for is proper lock up. The locking lugs are on the barrel. This issue can be corrected with a little patience. Triggers can be reworked to break like glass. Hinge pins can be loose which effects accuracy. There is a corrective solution for loose hinge pins.
Would I buy another TC Encore? Absolutely.
