Save yourself money... 66qt tub(15$)... flexwatt(5$)... 2 zilla hides(8$)... accurite thermometer (13$)... and you can go with the repti500 thermostat if youd like ... it does work just has a 5-7 degree fluctuation between when it turns off and turns back on... If you got the extra cash now i say just pick up a better one bc ur gonna have the snake for awhile. If you dont have the loot right now you can go with the repti500 and save for a better one or ask for one for chirstmas/bday/rashashanna haha whatever...If you have the tub in a warm enough room where the ambient temp is above 76 this is the only heat source you should need.
