Howdy, I think I must not have been clear about my experiance with condensation. I ran a hovabator last spring and found that the window was always covered in condensation. This was inside my house of course, but at that time I lived in Miami, Fl. My air conditioner was set to 68 degrees, and the hovabator was naturally at 89, this created alot of condensation of inside of the little window. Now keep in mind the window is a thin piece of plastic, not thick glass. I am sure the thick glass would keep temps separate enough to keep condesation down, but I was making a suggestion to keep the cost of the incubator down. I believe you said the glass you got was normally $70 or so, this is a big chunk of money simply to be able to see inside. I am sure there are many ways to keep condesation down and keep costs down as well, I would like to hear others thoughts on the subject. It is discussions like this that make all of our incubators better. On that note I have found a good resource for old fridges and freezers for free, it is a yahoo group called freecycle. There are groups all over the country, and you'd be amazed at what people offer all for free. Hope to see more suggestions and opinions, Matt
