I've had a broken 17-85IS for the last 6 months or so, and have finally got an estimate for repair. Apparently, it needs a new iris. The cost? £132. What's this lens worth at the moment? £200? Is it worth repairing? Bare in mind that I would probably be selling it at some point, as want to replace it with a 24-105IS. However, that may be a while yet, as I don't have a job at the moment
