I do want to recommend you get the largest hoop machine you can afford - even if you don't think you will ever need one that large, believe me you will. Embroidering with a machine becomes addictive and I use my largest hoop, which is 7.8 inches x 10.2 more than any other.
My machine came with the 4 x 4 and the 7 x 10. I bought the 5 x 7 with the magnets.
