Building one is not that hard. It can be fun, as well. If you send me a pm with your email address. I will be happy to send detailed instructions,on how I build them. Believe me you don't want to use one of those incubators. You are talking about. Besides you are thinking about one or two clutches. That want last long, you will be addicted to the whole breeding challenge just like the rest of us. So send me a pm I'll be glad to help you in any way I can.
