That's a good point, I had forgotten that. It does say not to run the humidity high. I did anyway and nothing bad happened but there was condensation in places there probably should not have been.
I think the best hatcher is a homemade one. After hatching a few times in the GQF Sportsman, I switched to the old Hovabator and Little Giant. The thing I didn't like about that was the horrific mess and if I opened it, all the warm, humid air dumped out on the floor and cool, dry air replaced it, making me very hesitant to take out chicks, but they were bowling with the partially hatched eggs and that seemed bad too.
I live the one I made, it can hold 120 eggs, more if I put in a second level of hatching cages. I keep the electronics outside sitting next to it, and run all the cords through the drain hole. I didn't bother to drill any holes at all, I keep the top slightly ajar and the inner sliding windows are intentionally not airtight.
The one I made is probably larger than you need, but it could be scaled down easily.
