I purchased a Brother from Costco to haul around to Guild etc. but I wore it out in a year. Bought a Janome and love it! The low shank feet from the Brother also fit perfectly on my Janome. I had a plastic darning foot but purchased a metal one for under $20 when I took a class from Jill Schumacher, "Quiltmaker to the Queen."
