Last year I bought 1 gravid female that laid 9 eggs, 6 slugs and 3 good eggs. I bought a micro fridge off of Craigs List and used 3 inch 10 watt heat tape controled by a VE-300 thermostat (from Reptile Basics) to incubate them. I filled empty soda cans with sand and sealed them with silicone sealant to great a thermal battery (instead of water, easier clean up if any leaked). This was really stable and had room for 2 clutches. This year, I built my own incubator from scratch. I designed it myself and spent close to $1,000 on it. It can hold over 25 clutches. I have successfully hatched 7 clutches so far and have 1 still in it. I have only lost 2 eggs, 1 egg was actually filled with only white and no yolk (no embryo in it) and the other died because of a twisted umbilical chord (I do not cut the eggs until the first hatchling in the clutch pips on its own). This incubator is constructed with multiple layers and also has many soda cans full of sand and sealed. It will hold it's temperature for over 1 day without power if I do not open the door. I can give more details (with dimensions and such) if anyone wants, however, I was in such a rush to build it, that I did not take good pictures during the build, so I have not writen it up in the DYI section. Here are some pictures:

This shows the incubator's inside. The top 4 shelves can hold (3) 12 quart tubs each, and the bottom 5 shelves can hold (4) 6 quart tubs each. You can see the soda cans full of sand at the bottom and on some unused shelves. I had 6 clutches in it at the time.


This is a detail picture of the door edge. It shows the layers, 1/8 inch melamine, 1 inch foam, 1/4 inch plywood, 1 inch wood frame with 1 inch foam between frame supports, and 1/4 inch plywood.


The door seal. 3 strips of "D" weather stipping on the two faces, on the face that meets the 1 inch foam in the above picture and on the face that meets the 1/4 inch plywood in the picture above.


Shows the depth of the incubator, a little less than 2 feet and the 3 draw claps. I used 2 door hinges on the other side.


Exterior, shows the height around 6 feet, width around 3 feet and the VE-300 proportional thermostat that controls and the VE-100 on/off thermostat that is the back-up.


As for incubators that you can purchase, I know a number of people, who are using Georgia Quail Farm incubators. They will adjust some of the features on the their bird incubators and make it specific to your application. The breeders I know using these are very pleased.
