I hatched some eggs with a hovabotor last year I got from LLL Reptile and it worked just fine. Cheap! Only issue was it is a bit small, I had to shop around to find a tuper wear container that would fit in it with the eggs in it. I put the tuper wear container in the Hovabotor, filled with Hatchrite, drilled a small hole in the side where I could put the the thermometer probe, and it worked out great. 6 out of 6 eggs hatched.
