I do have one question though!
What is the general consensus with the heating elements? This is the last piece of the puzzle I'm trying to figure out. I've already decided I don't want the hassle of light bulbs in any form and want to go with this:

I like the idea of a more uniform and efficient heat exchange with the radiator fins compared to the exposed nickel chromium wire, but I want to know how reliable it is. I believe ozexpat is using the latter choice, but I can't remember/ find if he said how well it worked. I am using a PID temp control with a solid state relay because the auto-tune feature seemed like a better choice to me if that helps with any suggestions! Thanks!!!

If you read how a ptc works you will find out in simple terms that its is designed to reach a max temperature then it will level off. This temperature is a lot higher than you will require for a incubator
good points: if something goes wrong like the fan fails it will max out on temp so there's less fire risk
bad points: turning on and off causes voltage spikes that will shorten the life of the unit
other points: keep a spare or like someone else on here suggested in a different post look at using a personal heater from walmart they are about $14 for a 200 watt which includes the ptc and a fan that way you know where to get a spare should you need one.
wire heater are easy to control, cheap to replace the wire, not affected by being turned on and off.
bad points: lots of people have set fire to home made incubators especially if the fan fails.
