We have to thank BK for responding here. I don't think you're thread hijacking but actually adding valuable info to this already hot topic.
Let's face it. If and when the TC sub finally arrives in our hands, it will definitely take the biggest share of the demand market with its supposed taking of gen movement, dial, hands and better SEL. It's not even an issue of supply. The high demand that it will generate because of its best features will and can make it in the WM9 second-hand market price range in the future due to its rarity.
But that doesn't mean BK is done. I actually do think he will (pardon to putting this on the third person BK) evolve and will build a better 99.9% sub.. Remember, never underestimate the guy with talent.
In the not so far future, we will be able to see a TC sub case (or whatever you wanna call it) with an improved SA3135 movement perfected by BK. That is only a matter of time. And it will benefit us all here.
