I have several gecko species, many leopard geckos, and I'd actually love to get into snakes -- I think they're fascinating creatures. This means I'd need different heat gradients and mechanisms for the different species...not to mention different sized cages.
I'm glad you said what you did -- darkness inside the cage is a problem for me. I'm looking for stackable viewing cages so racks are out for this endeavor. I have to admit, both the Boaphiles and the Showcases looked a bit dark. I'm sure the animals would like it but its not what I'm looking for. Plus, the Showcases are pretty hideous in my opinion.
Only problem is that the Boaphiles are most expensive. Still, I've heard the best things about them. Animal Plastics' heat mechanisms are a bit vague. Boaphile makes everything easier.
