Jeanneau and Beneteau are a start, also if you watch the classifieds you will see mast furling rigs from a refit for sale. Just do a search. You could also google mast furling problems.
I have been on two different boats where we had the main jam while trying to roll it in, in light winds yet. The skippers were experienced with in-mast furlers too. Some of the newer in-mast spars have a sail track along side the opening for the furling main allowing you to use a standard sail once you remove the furling sail.
They are convenient for a lot of people, and a lot of charter boats have them, so they must work OK for most people. I would say poor performance, shorter sail life and extra weight aloft are the big negatives for me.
