I suppose for $10k you could get a custom one made.
The 'bent that's recently caught my eye is the Optima Cougar - rear suspension for comfort, can be made fairly light with carbon boom, seat, and handlebars, and it's meant for going far and fast. Not too expensive either, compared to other Dutch 'bents.
