I spent about 3 years auditioning longarm machines (plus building an addition over our two car garage) before deciding on a purchase. It came down to two brands of machines which would both have had service representatives in my area...I was hesitant to purchase a used machine because of warranty and service. Even though you have gotten to try longarm machines at quilt shows, I suggest you take a few long arm classes that provide hours of free motion instructions and experience on a machine. I began my FMQ journey four years ago at MQX in Manchester, NH and fell in love...I knew someday I wanted my own machine and it finally got delivered a couple of days after Christmas.
