I definitely recommend that seller. You will probably want to splurge and get both of those feet I mentioned. They are not very expensive so it's really worth it. I use both of them all the time. I tried two other sellers before that and got wonky feet that didn't fit right - they were crooked when put on! Who wants to piece slightly off? Not me.
Also... if you don't like binding quilts, check out the binding attachment. The top clean bottom raw one is perfect for 2 1/2" strips folded in half. I have a youtube video on using it if it helps. A few people asked me to do a video of it. I can bind a massive quilt in no time now.. I hate hand stitching. I used to glue baste the bindings and that was awesome until I got the binder attachment.
