re: cost, I'll hazard a guess that it was the 'Neugart PLE 60 Planetary Gearbox' that blew the budget. A quick check on ebay says usd$750.

It's great to see good builds like this - I keep saying "one of these days". In my neck of the woods we have a pretty resource in the form of GRIN[0]. I believe Justin is a longtime participant on endless-sphere.
My latest build (on a Walmart special) was a BBS02 that probably rings in around the same cost but without the openness of this build.
