Which model Thompson Center Arms?

Had a original Contender way back when they first introduced the 35 Herrett (many, many years ago) but have not had one in years so which is the best model?

What I want from it:

* Replace my slug gun with a 20 TCA
* Replace my CVA 50 cal black powder
* Throw in a 300 H&H for fun

Since prices are all over the place do I buy a frame & stock and then barrels? or a one complete gun and add barrels?

Looking at the Pro Hunter as possible starting point
