Bloozoo he was RRP'd at £80, but I got an overall discount as I bought his tank, decor, hardware, food additives and everything else at the same time.
Housing space is more vertical-oriented than horizontal. I have a custom made front access 36x24x18 tank with ventilation panels added (don't put a cham into a standard aquarium), with heat lamp and UV.
Overall he cost me about £220 to get set up, then ongoing cost of replacing substrate once a month and feeding comes to £25 to £30. That £200 doesn't include an auto-mister because I'm around during the day to do it manually. Yes, they are definitely time consuming, far more "needy" than some other lizards, but he's worth every minute. If you have some specific questions let me know.
