They're great! I've taken a short break because my hand is sprain (note: from pilates! hold the weights the way you'd normally, not the way they do on the video! that's how I hurt my hand! Month of pain)! Anyway, they are sort of expensive, so I'd recommend the arms, abs, & "buns" ones first - or only. And maybe a book, or just the book. You can get them cheap from a bookclub, even the book by Winsor Pilates, the same as the video phenom.
