I wouldnt say its worthless but not worth the money you spend. If you really want one, i say craigslist it! just wait it out. Like what everybody else said, its better to build one your self. I have one because i wasnt thinking at the time. i could have spent the money in building a bigger and better one. I did made some modifications on mine tho. I guest that made it worht the money and it was fun. to each its own.
A baby Hermann's will outgrow that amazingly fast!\
Buy the biggest storage box you can find from Walmart, Target, Big Lots or whatever is handy, but at least 3' long by 18" wide (but bigger is better!), and make your new buddy a temporary/winter home.
Then start building a really nice outdoor home for it, because with good care, they grow fast!
