Basically, I want the least expensive therm that is reliable, THAT SAID, the Herpstat at spyder robotics is only about $20 more than the Ranco or Johnson prewired at reptilebasics. Do you feel I should spend on the proportional Herp now, because I'd want to upgrade later? My thoughts are, if it's worth it, if I'm already spending 80 I might as well spend 20 more and get a better unit...

Or, should I save my money and get a zoo med, alife, ect. because they work just as well for about 50-100 bucks cheaper?

I live in DC/VA, and the ambient temps of my apartment do vary quite a bit- it's an older place.

I am a full-time worker and student, and while I have money saved up, I don't like to blow it on things that are above the necessary, but I do obviously value the health of my snake and know first hand how much vet bills are!

Looking to purchase as SOON as possible, any input greatly appreciated! Sorry if long winded!
