I have the opportunity to purchase 2 GQF 1250's for $150.00. I just looked it up and I believe that model is a hatcher?? I'm wondering if I could convert tone to an incubator by putting in automatic turners? I'm new to the cabinet style. When I go to look at them this afternoon is there anything in particular I should be watching for? I've heard the seal breaks down over time, can I still buy replacement seal....is it worth the $??? Any info would be much appreciated!! Thanks!
