I'm thinking about picking up some thermostats (rather than using rheostats) for my cages. I know that Helix is the de facto standard for herping, but does anyone have any experience with the HerpStat (http://www.mgreptiles.com/Herpstat.html)? The base units have roughly the same features, but the HerpStat is about $30 (USD) less per unit than the Helix DBS-1000.

Comments?
Thanks.
