Well you got to think of it this way too, a T-stat is the single most important piece of equipment for your snake. It is going to deliver the right amount of heat to keep that snake alive and from getting cooked or frozen. So its not something you want to skimp on as the end results can cost you hundreds or a dead snake. I too use a Herpstat 1 and 2. Debating on a 4 or 6 after I get my 2 gals their new AP T13s as i'll then be focusing on a GTP and I will need another Herpstat lol.
