You can go to Family Dollar/General and get a picture frame for $1 and use that as your window...Also, a roll of hardware cloth is pretty expensive. I got some at a local mom-n-pop hardware store, they sokd it in rolls or per square foot. Try to find something like that, unless you have use for a whole roll!
Using someone's idea(not sure who) I am making it from a wooden box thingy and I am gonna screw a nail to a pole under it isoon and then make it so the ends of the pole stick out through the sides of the bator, that way I can just turn those and it will turn the box!
You might also try your local fish store, such as petland, or petsmart. They get some really nice coolers when fish arrive, and I left with 3 of them at no charge. These are simular to the LG but a little larger, would be great for incubators, and the price is perfect.
