We also picked up a Kelty Noah 12 x 12 for about $60 last summer. Another great option is to check out tent footprints. REI and Sierra Trading Post both sell them and you can sometimes find a really good deal on them. Just be sure to take note of the shape and size of the footprint to make sure it's large enough.
"Mother Gue", I says "the Rocky Mountains is the marrow of the world," and by God, I was right. Keep your nose in the wind and your eye along the skyline.
