I'm thinking there may not be a huge price difference between the 72 and 48 Bones, since the 1/48 is readilly available. I have one in the stash and the box takes up a lot of space! But I prefer 1/48 scale for everything except for a large assortment of WW1 planes that better get built while I can still see.
Gotta be a 72 scale B-1 out there--just sacrifice a leg, you need the arm to keep building!
As far as hubby goes, I bet he'd understand!
