I've been thinking about switching to herpstat just because I have stackable enclosures, and I've heard such great things about them, but I can't say anything bad about the Jumpstart brand. I've used several of them for the past 6 years and haven't had a single one fail on me yet (knock on wood). Considering the herpstat 6 is about $450 and the Jumpstart is about $30, I'd have to go through almost (15) Jumpstart units to reconcile the price difference. I understand the herpstat has more bells and whistles but I don't really need those.
