hatchrate has nothing to do with brand, it has to do with the operator preparing the eggs correctly and operating the incubator correctly which includes automatic ones. You need to read up on hatching first, sally sunshine does a nice instruction page you should download and read a few times.
Anything advertised is not worth buying. Golden rule.
There are generic kinds of 112 egg auto incubators on fleabay for $100-180 and with post they will be about 200-250 or so. A lot come up as being located in Australia, but they are not made there, so the same thing is available from the country of origin and should be able to be landed in the usa for the same money.
112 should be about what a home poultry hobbyist should want. Do not add extra eggs to an incubator once it has started running.
