Yeah... I would go with a Herpstat too, but I literally spent everything I had to spend on this for the supplies for the incubator, and the Herpstat is like $200 on the cheapest place I found it (eBay). And I could only afford the $18 Inkbird.
And in case your wondering why I put the geckos together if I couldn't afford the the top stuff for the incubator, I thought the Hova-Bator would be fine until I found out otherwise...
