For some nice but affordable caging you can't go wrong with BARRS caging.

I'm getting a female coastal on Tuesdayand I will have her housed in a 10 gallon (she is TINY) for a little while then go to a 24x12x12. Then a T5 and so on.....
If your not going to be able to provide proper caging for a JCP...as hard as it is....I would hold off. But I believe you will be able to properly house it. So I say go for it man and ENJOY!!!
