What kind of rack?

Alright.... I'm tossing around the idea of buying a rack for my 6 (for now) ball pythons. I keep them in my room, which typically stays at a somewhat cool temp year round.

My question is, which rack do you think is best for this type of environment?

I've heard folks talk about some brands of racks that have too many holes and are difficult to keep temps and humidity up. Just curios to know some of your opinions.

Thanks

Razz racks i think they are.. made of a pvc plastic sheet look slike a wood rack. I have my own made locally. they are pricey but the enclosed black plastic is awesome. stands up to anything and the snakes seem to really enjoy it :)

more important is whats your price range? home made wooden rack is <$100 once you get up there your looking at >$500 or or even 1000 plus :)

how about a future animal set? 6 for now but is 12 a possibility?
