$80 LG still air? Not very easy
$380 Brinsea? Idiot proof
This year was my first time. I started with the LG, and had horrendous results, but other people do just fine with them. What are your short and long term goals, and how much time do you have to babysit the incubator? If you are wanting to hatch a few for fun, or just run a few batches, spend a little less on the styrofoam, but I recommend the Hovabator over the LG. If this is something you will do over and over, and don't have time to babysit the incubator the first time, then a Brinsea is incredibly simple. Either way you go, practice makes perfect. You will learn more with each hatch
