Another vote here for the K-Drives. I've had them on the bike for a few months, and couldn't be more pleased. They are big, first of all. They lock onto the frame with a key, and come off in a moment. They seem to be quite strong and virtually waterproof, as well. A little pricey, but as in all things, you get what you pay for. You can get them from Brent at NewBonneville.com; he ships everywhere.
Here are a couple of pics of the bags on the bike, and one of the brackets when they are off the bike. Personally, I like the look; they are heavy, hugh-quality chrome.
