I started with this 1202 my friend lent me. I know some people don't think of a cabinet incubator as a "beginner's model", but that catchphrase says to me "easy to work with, with known book info" rather than "inexpensive". I'd rather put my money into a bator than shipped eggs that get messed up in incubation, extra gadgets for troubleshooting, etc and be able to test hatch by following guides like The Guide To Better Hatching, rather than trying my luck with lots of variables or trying to find someone with the exact same bator to ask.
There are deals out there on good used cabinet incubators; they don't have to break the bank.
