I'm not sure about how expensive these are from a buying perspective as I've never used anything crazier than water - but from a "machinists" point of view I can't help but thinking 125 is extremely excessive, I could make something similar using Alu round bar stock, and maybe 10 minutes time on the lathe or 15 minutes on the mill - and get a good level of precision. Since I have free access to these tools (as does nearly every other student) the only cost would be labour (aside from materials). And my guess of the material cost puts your labour at nearly $100, or $400/hour. Obviously the mounting hardware also has costs associated but, they appear to be minor to me.


Maybe I'm completely missing something you're doing in the design, or marketing process, but I'm just curious if you're getting ripped off by a machine shop, raking in the cash, or there's really something special in what you've got here.
