I've seen plenty of recommendations on here for using a T8 with a divider to house two adult BPs. The recommendation I've seen is a square foot of floor space per foot of length on the snake. Either way, I think the T3 has plenty space. Sure, it's more expensive, but not everyone has a good spot for a 4' cage, and it's a lot easier to find 36" stands to put it on that look good. The only thing I could find for my T8 was some janky looking industrial shelving.
