New replacement cost for all those lightly used sails would easily top the boat's asking price. Depending on condition the practice sails may even have some value. If you want a lightweight, no frills flyer to race, looks like a good boat.
agree sails worth more than boat but that is ok......old boats get cheaper but new sails just get more expensive.
the O29 will sail to it 's rating better than her sister the O30!
Pretty boat, good luck.
