I love my Brinsea Mini Advance (have 2 of them) I find it easy to monitor humidity with a small round reptile hygrometer, and I didn't want to have a huge capacity cause I know I would have it full. Having the two lets me put in a few eggs at a time, right now I'm waiting on Serama eggs to hatch, got the little egg holder for those. I tried an old model Brower, and a newer styrofoam Hovabator, didn't like them at all. Here in Canada, I ordered them from CBotkin, great shipping time and not exorbitant (not cheap either)
