Depends on your ambient temps...
I was told many times that I didn't need an UTH/Tstat because of my ambient temd (80/90 cold/hot days and 75/85 cold/hot nights), but I still got one cuz I like to turn on the AC A LOT!
Right now I can't see where you are (forum app), but if you REALLY need one, sure, buy it. You will prolly have some use for it later.
