You can also try Atlantic Sail Traders in Florida, they make new sails and sell used ones. Nice folks to work with.
The problem is, why did someone get rid of the old racing sail? Right, either it was shot, it wasn't flying right, or, what, the sail is perfectly good but the boat sank so they have sails to get rid of? (Unlikely but possible.)
AST has some glue-seamed foresails that are pretty competitive and not a whole lot more than "good" used sails. Try asking them about that, although glue doesn't seem to be as durable as sewn sails. (3-4 years instead of 5+)
The problem with used sails, is that even with a money-back guarantee, you lose two-way shipping if you return them. And that can really take a bite these days.
