hey y'all, i am currently in the process of getting a rack and i was wondering what kind of thermostat i need, i currently have a reptitemp 500r because i only have 2 tubs and it works fine, but i am currently looking to buy from animal plastics, probably their economic line with belly heat, now my question is, do i need a more modernized thermostat, or would the one i have now work?... thanx
