I'm fully capable of knowing whether or not I can afford an animal. I do not skimp on cost when it really matters. I just spent over $1,000 on my beloved ferret whom had cancer and recently had to be put down . I'm considering a BP again because I've been studying up in them for 6 years and I figured it'd be a good comfort to me. Perhaps I worded it wrong, how about the most affordable set-up. not everyone can afford to run out and buy a thermostat and I'm sure they still have snakes. I've had plenty of experience with animals of every sort and I don't just rush into things and then end up not being able to handle it.
Anyway, what about a Rheostat, would that work?
