Right now I'm just putting money into it as a hobby and keeping, not breeding. I'd love to get to the self-sustaining point, but I find myself drawn to boas more and more... which require more housing / food and can be harder to sell than BPs (plus larger clutch size), so I'm Leary of breeding.

I think I'll continue it as a small hobby for the next 4-5 years, acquiring new species and deciding exactly what I love, then I'll reconsider breeding.
