Have to agree, go proportional. Best money you will spend, and take away alot of worry and headache on setup. I use all 3, helix, Herpstat Pro, and Herpstat ND. Over time, I've been replacing my Helix with all Herpstats. More features, easier to program, built in nightdrop without extra equipment, etc.. Almost all of my Helix come up with error messages at one time or another over the years (but have kept correct temp), never had an issue with a Herpstat. And, they show and are programmable to .1 degree. I don't think that matters much, but another feature, might matter on an incubator.
