Looking into a Canopy

[asap2stacks]

I have a 23x20 concrete slab that's connected to my shop and I was thinking about getting a canopy and start working out there some times due to the heat inside my shop. Anyone have any suggestions on what I should get ? Need something I can leave up all summer with out having to worry about damage.

Harbor Freight sometimes has a good selection - Sears have some on sale at times too.
