I had bad luck with the LG that I picked up on a whim at TSC. I'm going to try to return it since I never felt I could control temp and humidity well and it is brand new since nothing actually hatched in it. Anyway, I need something more reliable and can't spend too much. I'm thinking of purchasing the Brinsea Mini Advance. This is not the EX, though, so humidity will not be automatically controlled. That one is a bit pricey for me. So I'm wondering how difficult it is to control the humidity with this model?
