So the Ranco prewired for 74$ would be the way to go???

On my setup I have a total of 3 UTH's one on the cold side(i have a cold room) and 2 ont he hot side. For the winter the hot side was fine being on all the time but now that spring is here i can see the temps rising. Cold side is running a repti temp 500r from petco. which seems to work very well.

Since I need to get a t-stat now for the hot side, should i just get teh double ranco and call it a day?
