The one I got for my 40 gal. tank was about $25. Yeah, they're more expensive than heat bulbs/lamps but they're wonderful for a nice, regulated temperature. I use mine on the cool side and it keeps it exactly between 80-83F 24/7. Definitely worth the cost. (be sure there's space under your tank/tub to allow air flow so it doesn't trap heat and cook your snake by accident!!)
if i got 1 it would be going outside the tank . your temps sound a bit to cold ?
