I own a pre '70's Leahy Famous Incubator Model 1200, made of 1 3/4" Redwood, 8 trays, good for 1000 eggs...21"W x 46"D x 54"H
I bought it to restore it and sell it after I have at least one hatch just for fun...I've been doing a lot of research on the subject of incubators and found out that GQF ran Leahy Bros out of business with their electronic thermostat unit. I'm not a fan of the white styro box's (over priced IMO)
I bought a lab incubator off of Craigs List....stainless with micro processor for thermostat...it holds heat well, but I haven't had time to mess with it yet.
