My experience about home made is that you really need to spend about $60 on the electronics, and then you still need a cabinet. You can come up with a dandy incubator for much cheaper than a top of the line cabinet incubator, but it is tough to make a good one for really cheap.
It's very difficult to make an egg turner at home. You have to be much more clever than I am with electric motors, gears, and building things. Buying a commercial egg turner costs money. Good quality thermostats cost money. Accurate thermometers cost money. It's not easy to come up with those things out of the junk pile for free.
