There just happen to be 3 old incubators for sale near me, and I'm wondering if any of them are worth getting. They're all on craigslist: Old Brower http://portland.craigslist.org/mlt/grd/1553506732.html Old Sears and Roebuck http://portland.craigslist.org/mlt/grd/1553458450.html This one's just called "heavy duty": http://salem.craigslist.org/grd/1557625571.html I was wondering if anyone had experience with any of them, especially the last one (because its the cheapest and closest). I'd love to get an incubator that actually holds steady temps. I assume they all would be still air, would you add a fan then? Thanks!
