just crunched numbers on them and one herpstat pro goes for $319 list price.
A corresponding helix system would be:
4 each Helix DBS 1000, 4 X $135 = $540
4 each night drop cord, 4 X $25 = $100
Total = $640 or literally TWICE the price of one Herpstat Pro!!
Note, that DOES NOT include longer temp probes OR timer unit to plug night drop cord into.
Don't get me wrong, I have a bunch of the helix units and really like them for individual use. The Herpstat Pro really shines when you have multiple heating zones that could be controlled from a central spot.
