Thanks for the replies so far.

If we get a BD, I would build him a nice 4'x18" cage (I would go to 2', but that would be too wide in this apt.).
If a box turtle, since we live in an apt. I would get him a nice big trough tub or really large rubbermaid tub. I used to have a handmade pen outside (8'x4'x6' hardware cloth/wood buried 4' deep with a hinged lid) that I kept 3 in back in ElPaso, and I wish I could do that here.

I would be more able to give a BD a nice variety now, since I have a BTS and a Leo gecko. The Leo eats a nice mix of worms and bugs, and the skink eats the bugs as well as spring mix greens, fruits, and meats (currently cat food, but I'm weaning him off of it - he lived 5 yrs on only kitten food). A BD or a box turtle would fit into that feeding range nicely.

We both love BDs, but Ari doesn't want that horrible smell in the apt. again. That's why we have animals that don't have odors.

So, any other input on this? Does anyone else have a dragon that stinks?
