Need a new enclosure, any ideas?

Hey guys,

My bp just broke her 3ft mark. (joy! :)) However, I'm in desperate need for a new terrarium/enclosure. I've ran into some financial trouble, and I'm pretty sure she's outgrown her 40 gallon tank. So I'm looking for anyone who might know of a good deal on a bigger tank, or have one they're willing to part with for a decent price, or point me in the right direction? Been doing my own shopping around, but I'll take any advise/help I can get. Thanks my my fellow herpers and herpettes.
