I went to Lowes and had them cut a sheet of plexiglass, and a $2.00 cabinet knob. I got my insulation board from Hobby Lobby, it's was cheaper and they have 40% off all the time. The thing I like so far on my tank is that I can slide the plexi glass forward and back to adjust ventilation and humidity.
I still can't get images to post from my gallary. If you look at page 5 of this thread you can see it or search for my gallary.
