Here are some costs for comparision: Please note that I do not list prices where there are issues with US export
Stevens 200 with the bolt head you want to shoot. Not so easy to get bolt heads. You can modify the stock to suit (dirt cheap) or sell off the various parts you will not be using. One a new rifle, figure on recoup $100 to $150 on parts. Est $200 for bare action.
Timney pre-accutrigger $150
SSS and RB2 are other options
Barrels: Shilen SS Select match $455. McGowen SS $450 (plus $65 if they need to get the reamer). I can help with the install.
Stock: If you build off the factory or use the factory, not much. If you have to buy a stock, figure $200 to 600+ depending on the bells and whistles.
Base: I use Farrell 1pc MOA steel base $100
Rings: I use Burris Sig ZEE rings 1" $45, Shim kit is $15. 30mm rings $75 and include a pair of 10 thou shims.
Bedding; $75 and up. I can help here
Bolt timing: This allows for a much easier, smoother and lighter bolt lift. Doesn't improve accuracy but sure does function/cycling. This is important when shooting prone so you don't move your rifle all over the place trying to work the action. $65. Pretty sure I am the only one in Canada.
Oversized bolt kno

Again, it is about ease of function. Allen Gun works makes a nice addition. ATR does similar work. Radical made some really nice alloy bolt knobs. Guntech does install and maybe makes them too?. And I am sure there are others. $75 and up.
Add up the parts costs and you are very similar to a Factory Savage w/accutrigger BUT you have a much better shooting barrel and the option to choose wildcat chamberings.
