I'm in the performance automotive industry, and we often make and sell Delrin parts ("we" includes our partner companies in the US) that are CNC machined, and about the same size as the Reticle-Tru, for roughly $30, which is about what I would expect to pay for this tool.

Not criticizing, just trying to give initial feedback on the pricing structure.

I agree with GW that an injection-molded version for roughly 30-50% of the cost of the Delrin model would target a much larger market. Hopefully Jerry can eventually produce such a model.
