I ended up adding a 100 watt CHE and a fogger. I tried to make it as simple and cheap as possible, but the snakes health comes first.
Everything is perfect now. 78 on the cool side, about 81-85 warm side, and 90 for belly warmth. I have to keep the fogger on about 75% of the time to keep the humidity at 60% so I am sure the zoo med fogger I bought will bow out soon enough. I didn't know it when I bought it, but they aren't exactly known for their reliability.
