Death of a lens

My basic workhorse camera lens has reached the end of a long, painful death. It covered the medium-to-wide range (18-55mm), and it is damn difficult to photograph city buildings without it!

If anyone out there has a spare wide-angle lens for a Canon Digital Rebel they need to get rid of, or knows where I can pick up one on the cheap, drop me a line. This was the style of my old one, but anything that covers the 18mm zoom region would be swell.
