I have a chance to buy one that has been used only once. (Not sure if there's a significance there...) I have read posts about it being rather touchy. A review on Amazon stated that she only got one chick out of a batch & she felt that the temp fluctuated too much. Two questions: Is this a poor choice for novices? What is a fair price for the 'bator & an egg turner? I want to get into a good unit for less than $100 Thank you BYC friends!
