If you fancy the classic look, check this company out from the USA...Saddleback Leather. I own two of their classic suitcases (lg and med) and they're fantastic. Not only do they look phenomenal, they are truly functional and take a beating. I've actually lent them both out to a friend and it looked great on the back rack of his Mog. They're perfectly waterproof(by way of their construction) and are a great "investment" piece of luggage. Shipping may be prohibitive if the already high price isn't.
Wonderful stuff, but somewhat costly, even for a Mog owner...
