There was one sorry SOB on queensnake's chameleon forum that had the whole apparatus for a single veiled cham. I think he'd spent somewhere around $2000 on the whole thing. Apparently its not dummy proof, because his animal suffered from one ailment after another until it finally died. The guy had more $$ than brains and thought the system would look after his cham and he'd never have to be around.
Revenge is a dish best served cold...
With a side plate of steaming entrails,
And a nice Bordeaux!
