I'm researching Brinsea incubators because I got money to buy one for my Christmas present! What is the difference between the Mini Advance and the Mini II Advance? They both have temperature displays and automatic egg turning. Is it just the humidity display and the external humidity top off spout on the Mini II? Would it be better to get a smaller one like the Mini II Advance EX with the humidity pump so it's fully automated, or the Octagon 20 Advance without a humidity pump for about the same price but not having automated humidity control? Any recommendations? Or is there a better incubator altogether for a similar or lower price range?
