Well Jacob beat me to the answer lol. They are on sale now like he said. And personally if you think you are going to get more snakes, then i would almost just spring for a Herpstat 4. But otherwise, i would go for a Herpstat 2 over a 1. The cost isnt that much more and it will give you options if you need it. Or you can go all out like i did and get a Herpstat 6 which are awesome. They are huge though, like the size of a laptop haha.
