Here's my dilemma. I've been using a dinosaur cheap thermostat for several years, and it's worked perfectly fine for me. I have that on a 41 qt rack with 11" flexwatt.
I'm in the process of making a 28 qt rack. I'm thinking the 6" flexwatt, or would 11" be fine? (not running it lengthwise)
If I go with the 6" I'm going to need to get another thermostat. What would you recommend? I've heard herpstat, helix, and ranco are some of the best. I'm also not looking to spend a ton of money but I also know a thermostat isn't something to skimp on. I don't need any extras though, just the basics
It would be awesome if there was a thermostat that I could plug 2 diff size flexwatts into but I don't think that's possible right? Because the different size flexwatts have different watt outputs?

So basically, what size flexwatt would you use for a 28qt rack, and what would be your most highly recommended thermostat that isn't overlypricey?
