I had an AP T-11. Nice cage, a bit big for a bp but it did the job.
I used the silcone they sent me and sealed all insides where there were joints and it never leaked or smelled. I laid a nice thick bead along the seams. Anyway I had the heatcable just on the hot side and still had to use heat lamps to keep the temps up and then of course that killed the humidity. I eventually got it all fine tuned but it was way to much work to maintain. I was into the whole display deal also but w/ bp's all you are really displaying is hides and cage decorations . If I was to do that again I would have heat cable on the hot and on the cold and set up two Helix's, one each side.
I since purchased a Boaphile rack and I really like it. No problems, It took me about 5 weeks to get it and anytime I needed to speak w/ Jeff I just left a message and he called me back that evening.
I got a good look at Herp Enclosures at the show Sat. and they are very nice racks. And I have spoken w/ Rich from there and he is a great guy to work w/. I had a rack all planned and set up a way I wanted but had to cancel due to some other things coming up. I plan on getting that rack after the first of the year and I will buy from Herp Enclosures.
Do yourself a favor and check them out and give them a call. You will be glad you did.
