Anyone use one before?

Nope, I use a Matrix; works well enough for the price.

I have never used one but I just got a e-mail from midway usa and they have them for 100.00 off until the 31st.

I have about 40 of the Brick House models from Ameristep. They are very nice, but very fragile. They break easily and the zippers break alot. They are fine if you baby them. For $100 dollars they are well worth it, but wont take heavy winds or rough handling.
