What sort of styles are you looking for? I've bought quite a few for ballroom & dance - most skating ones that I've used for bodice/sleeves with a self-drafted skirt. I get them as printed patterns from Habithat, their UK importer.
I like them a lot - they're great to hack as one pattern will usually fit together with another using the same size and, being nested, it's easy to move from one size line to another when altering for varying body sizes. I like the big format and the quality of paper that they're printed on is excellent and withstands folding and unfolding over and over again really well.
