Sewing/piecing....quilting....embroidery.....all 3? You must have a lot of time and patience to do and learn all three. It sounds like you need at least two new machines if not three. For me, pick two. Long arm qypuilting is not one of them.
. I am happy with my combo machine. (janome 9900). I rarely have time to do embroidery but I still work full time. It will be fun to follow this thread.
