For possibility #1, you should always have a back up in case your mom wants to act up. Lol seriously though! Building one is fun and to me it's all about the experience in making one. I can't build crap from scratch and really this was to me the most easiest thing to make. After you build your first one all youll need is new flex watt for how ever big your next incubator might be. You gotta start somewhere.
