I use a Herpstat 1 for my RHP in my boa cage and a Hydrofarm for the UTH on my BP cage and honestly, other than the clicking the Hydrofarm makes when it comes on or goes off, it seems to work pretty good. It has a swing of 0.7f which isn't too bad for a $30 thermostat. I use a lamp dimmer for my CHE on the bp cage. Really its your call. The herpstats are really nice and have lots of bells and whistles but unless you are planning on using all that, hard to beat the price of the hydrofarm to just run your UTH. Now the Herpstat has more safety features while the Hydrofarm has one where it will shut down if the temp goes over 108f. The main advantage for the Herpstat is the proportional dimming feature which is a big plus for RHPs, CHEs and pretty much required if you want to use it on heat lamps. But like I said, your call, if you got the cash go for the Herpstat, you wont regret it but if you are strapped and need something, the Hydrofarm fits the bill nicely assuming like I said, you plan to only run the UTH with it.
