Cheap means the lowest that i can get if for a resin kit. This is much bigger than the bandai re issues (which i call 1/100 IMO) and bigger than Capt's by like 10 percent or so. I won't know real #'s until i get a material cost on my end. As usual i am not including any of the scratchbuilding labor into my equation.
As for variations, yes i want to do the small and large missile carriers, I prefer the large so will likely do that first. I absolutely love the scout, but that is a much more complicated conversion and while i do expect to get to it, that may be a while.
