DiStefano 3D Print
Ben; have you seen what DiStefano has been doing? Originally he was selling through Shapeways exclusively, now it appears he may be out on his own (or at least partially). His quad BOFORS in 1:72 was nice, but some items were below the then level of technology. His 20mm Oerlikon and MK51 director suffered in shipping as being too fragile.
I am a proponent of 3D printing in modeling. I think that is the way of the future.
