Glad you like it! We've got a fresh supply of #20 drill bits coming in from McMaster, so we may do just that depending on time and priorities. The first batch came out pretty well--only one really missed hole on a longer piece (which, invariably, will be the one hole we need...), but it's working out nicely even on the longer pieces.

Mind you, there are absolutely times where VersaFrame makes more sense than WorseAFrame; if you're buying 10' lengths of 1x1 tubing at your local hardware store (about $30 at last check of Lowe's), there isn't much cost savings until you factor in shipping. Even then, there's a certain point where the shipping can be amortized across enough pieces to still make VersaFrame worth it. (UPS Ground for four 59-inch lengths of 1x1 VersaFrame is $17.88, so about nine bucks and three days to have about 10' of tubing with holes at your door. At six lengths, $7.67/10ft.) If you have a source on cheaper/donated metal, then the math changes entirely.

Every team will place its own value on time, money, manpower, and machining resources, but those kinds of decisions are just part of the real world. (I'm not an engineer by any means, just a marketing guy at a car dealership, and we face with this same in-house/outsource decision often as well!)
