Well, I'd argue that DSN's 202/A is "good" out of the box, goin.
However, if you want a GREAT one, you will need to spend some ducats, Franke.
I just went through this excercise with another member via email and if you're building one with real DLC coating, an FGD dial, a t48 crown, Jakob caseback and an upgraded CG, plan on spending about $1000 USD, plus labor. Perhaps more if you want to use one of the pending Pre-V cases from one of the guys at RWGjr, a LH crown guard, etc.
