I've been looking into buying a disc brake lock. Are there particular ones that are better than others?
Avoid the ones that have a lock/key shape of a small circle. A while back one of the U.K. bike magazines had an article saying that these locks could be opened with a ballpoint pen. Whatever you do buy, get a reminder tag as well. One end goes through the lock, the other end you put on the handlebars. Saves any embarrassing 'ride away with disc lock still attatched' moments.
