BUY! My husband bought me one for Christmas and you wouldn't believe the time that it saves. If you go to sewforless.com they had one on there for $199 and a bunch of dies on sale! As far as what to get, I started with the ones I know I will use all the time- 6.5in square, double wedding ring, and the 2.5in strip cutter for all my binding. The circles are on my list too...actually I have a HUGE list, but I would suggest starting with the basic shapes/ favorite quilt tools and branch out from there. I haven't really tried any of the applique dies yet either.
