Sanddrag - the gears actually don't cost that much. Keep looking around for suppliers. These gears can be purchased, off the shelf, for about $90. Two sources that I used are Martin Gear (20 pitch, purchased through Applied Industrial) and Rino Mechanical (32 pitch, purchased direct).

I was a little off. I actually came up to $205 for each gearbox using gears from Berg and SPI. My 20 pitch gears were in the following tooth counts 16, 40, 60,20, 80. I plan to use bigger gears than you did for some slightly different ratios. That 80T gear is like 75 bucks alone from Berg. I'll check with your suppliers if and when my team builds this thing.

As for your note about the CNC machines, HAAS are wonderful. They are such a joy to work with and so user friendly. (I am just starting out on one).
