I was actually thinking of going for an 18" tall one, so I could add some climbing elements for her. And you are right, even with my skinny arms, it's a pain to clean the 1' tall one. The builder I was thinking of uses Vivarium Electronics radiant heat panels - are those good? I'm in Canada, and not all U.S. companies ship here. I may give the builder a call to chat about proper heating for an enclosure for my ball python.
