L.Brown, you make valid points. A labor intensive product is a challenge. Over the years I tried to tackle this problem and now with rapid prototyping etc it looks like it might reach prototype stage.
To get to a reasonably priced double that feels and balances as a best should is possible, I believe, as long as it is not expected to have the usual luxury touches. Opt out of auto ejectors, self opening, and some other things and it is possible to get a superb double at less than 2000 Euros.
Even at that price it will not attract a bunch of buyers. But it is worth trying I believe.
