I may also be able to help with a machining quote, I am the director of engineering at Wauseon Machine and Mfg. We build industrial machine tools and do contract machining. You can look us up on the web.
We've started machining the first batch of small parts. Once we have big parts done, I'll post detailed photos and final price at which point I'll request that everyone interested PM me with their details. Depending on how things go, we may be start shipping within a week and a half.
