36" x 36" Utility Window $89.99
Tilt-wash Double-Hung Anderson Window (no size & price)
Upon looking at the Anderson Window website, it seems that all their windows cost more than we're looking to spend.
E-mailed about Phillips Aluminum Exterior Windows to find out if they are tempered.
Edit: It turns out that ALL of their windows are tempered. Woo!
32" x 15" ThermaStar by Pella Basement window $64.00
From what I'm finding online, I think it would probably be best to go with ordering some tempered glass windows from Home Depot. Perhaps something like these.
