these would be higher than that, but what i have in mind i can modify easy to fit the applications needed. it would be more expensive than most 40 egg units on the market, but less than anything holding 100 or more eggs that i can find easy. im thinking about using a similar turner design to the one ive designed for my larger incubator, but on a smaller scale. the mechanics, less metal and wood would cost about $80 so im guessing a complete unit would be around $175 for a 100 egg incubator.
