Help!

I've set up the forced air fan Hovabator that I've used the last 2 years. Everything is set to go in that classroom. Just pulled out the other Hovabator that a teacher had given me from a Guilderland school. Thought it was the same as mine. I see that it is "STILL AIR"! I'm feeling very insecure about using that as my experience has not been with that. It sounds much more difficult to regulate temp and humidity with that. Have it plugged in to see how its going to register. Does anyone have a forced air incubator they will not be using for the next month? I'm very nervous now. Should I just go out and buy one? If I had realized that it was still air, I would have ordered one on line. Now I'm not sure what to do. Can I buy a reasonable one locally?
