Need Shade For Our Back Yard

We have been looking around for different ways to shade our back deck from the summer sun. One of the options we have found seems pretty cool and economical - a retractable awning for our home. It looks like there are a bunch of different manufacturers for them and most seem to have the same basic folding arm and Sunbrella canvas topset up and styling. We are really impressed with the Taylor Made Awning retractable awnings products and prices the most. We would be really interested in hearing has anyone else has had experience with these awning products?
