Herpstat or Helix for incubator?

[Aes_Sidhe]

I am a big fan of Herpstat and use them for my racks and incubator, the only difference is that I use this one for my rack http://www.spyderrobotics.com/products/herpstat.html since you don't need the ND feature for incubator.

I use exactly the same for my Rack as Deb show... and love it !!!! But like people says it really doesn't matter both brands made great and reliable stats.
