I'd look at Tartans, Bristols, Cape Dorys and even Endeavor and Irwins in the size you are looking for.
Tartan sailboats for sale by owner.
I happen to own a Tartan 27' so I am biased but there should be some available for pretty cheap and they are good sailors but usually need some TLC. I also like the T34C or any older Tartan like a T30.
Pearson also made very solid hulls for the most part so I'd include them too.
I've got nothing against Bentahuntalina's but there are so many of them around in good shape which will not be project boats.
Good luck in your search.
