I hated to do it ... but I actually bought a beehive super box from LittleGiant. It accomodated my present problem, but hopefully I won't need to do that very often. It is much more fun to make things in the shop. (I think)
Hopefully this is helpful if your new to beekeeping and need to buy a box.
If you are handy, the pre-made boxes that you assemble are great. Dadant is one of the best for that.
