You guys are killing me. Where are you looking under on Craigslist. I hardly ever see incubators on there. The last one I saw was a good price but just didn't appear to be no more then furniture. Didn't see a plug.
I have a Farm Master also. Just fired it up two days ago. It's has held temp since we fired it up, of coarse after we got the temp stable. I love it. Bought it for 175 with a brooder. My only does 200 eggs and I just got an order for 200 chicks.
