Your current stat is pretty decent from what a lot of people say. I'm sold on Herpstats but a Herp II would be great for both cages if you want.
Pro-Line is from Constrictors NW. He has a forum like this reptileinsider.com You can check with breeders there that use the caging.
I just think the plastic of the cage is the best stuff around. Watch the video he has on putting the cage together. Its super easy.
Best of luck.
You are doing this the right way be researching ahead of time.
