What should I ask this guy. He has two. One that is 30$ that has the egg rotater and one that is 15 that does not. Are there other items that I should ask about? I noticed on this board people always fussing over temp gauges and such. Is this something that normally comes with an incubator or do I need to buy it seperate? I'm in an email conversatioin right now with him so pardon my horrible typing skills at the moment. Any help would be appreciated...
