Craigslist is a good idea, but for my first, i just went with the cheapest I could find, a Hova Bator, model 1602N. I got mine for $35 and for incubators, thats cheap. It's a simple syrofoam incubator, you can buy extras like automatic turners, and fans, but I didn't and had 19 chicks hatch out of 20 eggs, so it did a great job. I still use it 5 years later and it still gives me great hatch rates. Also if you have never hatched before it comes with great step by step instructions made for that particular incubator, which is very helpful. Thats my opinion.
