I am selling one of my r com 20 incubators. It is really like new as I have never incubated in it. I just other day, got it out of the box and fired it up for the first time because I had lots of eggs coming but got my new-to-me Sportsman 1502 going so I REALLY don't need it... and my other R-com 20 is my back-up. How did I get two??? well, I ordered one for me for my birthday last year as a present to myself.... and my daughter got me one for my birthday last year... as a surprise... lol I decided to keep it as a back-up. So.... I am going to sell the r-com that I have never used. The humidity sponge never even got wet. It was stored in the orginal box until last week. I have the manual. Comes with the universal egg tray and dividers. I have had really good hatches with my other r-com 20. The calibration isn't quite what the manufacture says for humidity but once you understand that and adjust... it is pretty much a "set it and forget it". Asking $275 plus shipping.
