I own a Derbi. It's an awesome scooter. Unfortunately, Piaggio (the parent company to Vespa) purchased the company and yanked them out of the USA. I guess they figured that having two brands (Vespa and Piaggio) was enough in the US since the scooter demand is fairly low. Since then, trying to find parts is damn near impossible. I needed new break rotors a few years ago and had to order them from the UK. Shipping cost more then the breaks.
