How many eggs do you want to hatch at a time? If small numbers, I would definitely consider the Brinsea Mini Advance. While it only holds 7 eggs at a time, you get to watch them hatch and all you do is set it up and fill the appropriate water reservoirs. It does everything else for you. I am setting my 4th hatch this weekend and it has been trouble free thus far. My hatches have been 5/7, 4/7, and 7/7...the ones that didn't hatch were either not fertile or had other problems...not the fault of the 'bator.
