I love racks! Now that I own one I wont go back to using terrariums. They're much easier to regulate - especially if you buy one from a reputable builder such as the one you are getting.
Just for the record I wasn't trying to discredit your methods - just simply pointing out some of my own concerns. I had a lot of problems maintaining the husbandry in our glass tank when the girlfriend and I got our first BP - we didn't even know that we needed a thermostat! LOL This site helped a lot and I learned all the things I could improve on and how to improve them.
Regards!
Chris.
