I bought a set from Willie & Max:
http://www.willieandmax.com/Store/TraditionalStyleSaddlebags/tabid/126/List/0/CategoryID/1/Level/1/Default.aspx?SortField=ProductName,ProductNameThey're quite nice, they have a system which slings beneath the seat, but with zip-off connections which allow them to somewhat easily be removed. I also used metal brackets to keep them away from my wheel. I also used web straps, slung over the top of my seat, to lift my bags up. The web straps were made by my wife, and they are not necessary, but they really helped keep the system neat, and orderly.
The quality of Willie & Max is excellent. They are
not leather, but some sort of plastic, which is very much like thick leather. They are easy to clean, easy to use, and durable. I would buy them again, if I needed a soft set. Cheers!
