I just bought a used P19 genoa. Paid $100 and am completely satisfied. In
the condition it was in, even more would have been justified.
Roger Metcalf recently had a genoa built by a place in Edgewood or puyallup
or somewhere for a little over $200.
CDI (division of North Sails) can build a nice mylar/dacron laminate
performance genoa sail for about what IM gets for a new Odyssey genoa.
Odyssey won't sell Potter sails direct to the public.
The added drive of a P19 genoa is a welcome improvement in almost all but
the windiest conditions. With enough live ballast you can carry it in a
remarkable amount of wind.
