I'm looking into getting a few. What size would be big enough to house an adult female? 24x18x12, 30x16x16, or 35x23x12? And the only heating options are radiant heat panels. Could flexwatt be installed underneath just as effectively?

Here's a link to the caging page:

Also, they seem to be much cheaper than the norm. Is this reflected in their quality?
Thanks
