It would have been nice to have an idea of what lens you are acyually hoping to buy as some of them represent better value than others second hand. For instance if you're looking at a Canon 24 - 105mm IS L or a 100mm Macro you're probably not going to save much as they hold their value very well. On the other hand there are other lenses which lose a disproportionately higher value, the 17 - 55mm f/2.8 has fetched as little as £450 on Ebay recently, a loss of nearly £300 for the original buyer.
When you intend to buy second hand it's absolutely essential you know the lowest price for the item new, there are plenty of dreamers looking for far too much money, don't be tempted, there's one born every minute! Use Camera price buster to get a feel for the best new prices.
As for a faulty lens just what are you expecting might go wrong? They're pretty simple things in terms of construction, and broken elements are easy to spot! equally if the focus motor has gone or the aperture, it really will be immediately noticeable. The only 'fault' which won't be immediately apparant is manufacturing tolerance, where perhaps elements are slightly missaligned, but if you're using a crop sensor you probably won't ever notice.
Even if you buy a faulty lens a seller such as Ebay will protect you as the fault must be clearly stated in the listing, if it is not Ebay / Paypal will refund your money, however if you have bought a real bargain you might not want to return it, and instead opt for a repair. Sigma charge less than £100 for repair of most lenses, so it's important to bear in mind that repair might not be as disasterous as is sometimes thought.
I've bought lots of second hand lenses (and sold plenty too) the latest one was bought so cheap that when I discovered it had a problem with the alignment of the elements I chose to have it sent to Japan for repair, at a cost of £155 it's still a fantastic bargain & I know I'll get a lens which should be as good as new!
