Congrats on the nursing degree! I've been a nurse (BSN) for 15yrs, and still remember the immense relief when finishing school. My suggestions for you to look at are the Janome 6600, Pfaff Smarter C1100Pro, or a used Bernina. You can piece on a $50 vintage Singer, but I suggest you get something that you can grow into and that makes it easier and even more fun. I have several machines, and love the built-in dual feed on my Pfaffs. I got a used Bernina 440, and though it doesn't have the built-in dual feed, it's also a joy to sew on. Happy hunting!
