This lens turns up on the Canon refurbishment site from time to time. Set up an alert on SlickDelas for when the Canon refurb site advertises. When they advertise they have almost everything in site or just keep checking back. By buying from Canon you know you have a lens that has been checked out by Canon and is perfectly clean. One usually turns up every month of so: http://shop.usa.canon.com/webapp/wcs/stores/servlet/subCategorySort_10051_10051_-1_22751_highPrice_list#
Good to know. I created an account and put it on my wish list. When it becomes available, will I get emailed directly from that list?
