I also would not keep a pet in a tub, but I enjoy watching mine and creating a very natural habitat. I started with a tank, and while difficult to maintain humidity - it was not impossible, just took a little more work. But I had always planned on moving to an Animal plastics cage, and I LOVE IT. They are a great company and can work some customization in as well. They are nice looking and easy cages to maintain.
AP also has sales frequently. Just make sure you add up any custom changes, the base price is for the cage *without* any heating, locks, lights, or other extra stuff. It also can take a while for them to make and ship it - mine took 12 weeks, but it was well worth the wait and I wasn't in a hurry.
I too like how they look. Please tell how they are easier to maintain than a tank? Also how you overcame the humidity hurdle with a tank? I'd guess you had a screen top for the tank?
