I got a package of ten as a door prize at a quilt quilt meeting and I use them now every time I add my binding. Pricey, yes indeed but I don't need 50 of them. The ten I have is sufficient. I do like them particularly when traveling with an unfinished project. I always seemed to snag my self with the pins, ouch! and just not so with the clips. If you can find them cheaper, then go for it, but I really like them and use them on every quilt.
