Looking for recommendations for a heating mat/wrap for a Spike CF5

[Nokt]

So i have my CF5 in the fridge now and its keeping cool at 65F. Now I need a heat source for it. The Spike one is nice but i'm too cheap.

I looked around to see if there was any good cheaper options but I just went with the one from spike. It works really well and fits perfectly so I think it's probably just worth biting the bullet.

So I decided to give this a try. For $10 it's worth a shot. I think that I can run it down the side of the fermenter and then wrap it around the cone.
