I purchased a Brinsea Octagon 20 MK.II incubator 2nd hand, I figured it was a good deal since it also had the auto-turner. I payed $75.....I'm hoping it will work ok. It's not the prettiest. I'm half thinking I should have waited to buy one new. But, I guess if it hatches successfully that is all that matters. Does anyone still use this model? What is your experience? Any tips? Mine has no manual, this will be our 1st time using an incubator.
