FWIW, we usually get 27 feet of 1x1" thin wall tubing for $30-something ($40-something one year) when we buy it in bulk and pick it up from our supplier ourselves. Even small
online orders are substantially less expensive than VersaFrame. To me, VersaFrame isn't economical if the team can handle appropriate drilling of holes themselves. I agree it is very quick when used with the VEX gussets - but at a price.
2x1" is a bit more worth it due to the ability to make a very quick, easy-to-connect-to, precise drive train in many cases - but again, plenty of teams are better of using their skills to cut into bulk 2x1" rather than the VersaFrame. Personally, my team may or may not have a welder this year, so we may use Versaframe due to the gussets.
Not that VersaFrame is a bad deal under certain circumstances (valuation of time during FRC is hard...). However I think it's worth it to point out the tradeoffs in this type of thread.
