I think in this case even if a lot of people jumped on the vintage items exclusively, it's still the case of "a rising tide raises all boats". If the interest is there it can't help but benefit all aspects of the hobby.

Back on topic ... So we have an example of a company already offering something similar (the PRC Sprite). Based off of the discussion so far I think a $100 - 140 (yes, i raised the price a touch) razor is doable and could sustain a business if a large enough quantity was produced/sold. I think there already is a market for a quality basic straight as every year I see posts from people looking to buy a razor but finding stores sold put.
