Hello! I am no longer hatching eggs and need to rid myself of the temptation. The octagon 20 holds about 2 dozen eggs depending on size of the eggs. Hold temps PERFECTLY, you never have to adjust once you get it set. I had some great hatches out of it. I've had it for about 2(?) years so it has some discoloration on the inside and smells a little funny but still works and looks great. I don't have all of the egg holder wires but I have enough to be usable. I purchased it for $250 and I'm selling it for $100. DOES NOT INCLUDE AUTOTURNER. You can though order one seperately from Brinsea.
