I have to decide between a Q (80 CF) or a K (244 CF) for the oxygen and a #2 or #3 acetylene. I'm probably going to go with the Q and #2. The tanks are only $180 each plus the gas fill. If I decide to go bigger in the future, they will credit the purchase price of the smaller tank to the purchase of a larger tank. But, if I find the tanks limiting, I'd likely just buy a second set.
That is a good size and easy to transport.
