Sigma 18-250mm f/6.3 - enjoy while it lasts

In October of 2009 I picked up a Sigma 18-250 f/6.3 for my 7D for walk-arounds, so I could shoot any scene without having to switch lenses. My choice was between Sigma 18-250 f/6.3 and Tamron 18-270 f/6.3. The latter didn't have an ultrasonic motor at the time and wasn't focusing as fast as I wanted, so I bought the Sigma 18-250 for about $800 CAD.
