styrofoam incubators have a lot of supporters out there, and for someone one a budget, as long as it has the circulation fan and you get an egg turner so you can leave them alone, you will be okay. I had one for years and by best hatch was like 50%. I lucked out in getting a cabinet and my hatches have never been less that 90% since, but if you get a styrofoam to work like some people i know can, they are a steal for the amount of use you can get out of it. go with the one with the fan though, you'll double your hatches in some cases. good luck
