Yes there are 4 companies (I know of) that sell multiple probed T-stats The herpstat 2 from spyder robotics (my pick personally) http://spyderrobotics.com/home/products.html
The Ecozone it has a few more features (web reporting!!) and has more variety but is pricy (as the components are separate) http://ecozonevivarium.com/products-...ntrollers.aspx
The herpkeeper by digital aquatics this is a very flexible unit but it has confusing parts and lots of variations. (addable components. I have only seen the fish keeper I have never touched a herpkeeper) http://www.digitalaquatics.com/herpetology/systems
The VE300x2 this one has the least amount of features it is simplistic compared to the others. http://www.vivariumelectronics.com/
