I have the Janome binder attachment and love it. It was pricey, over $100, but has been totally worth it since I can't do handwork for any extended length of time. The corners took some practice but are working out fine. Finishing the end has also been a learning curve but I'm getting there. I've bound at least 11 quilts with it since September. I definitely can't bind a quilt in five minutes but I can get it done in about 30 to 45 minutes, sometimes less depending on the size of the quilt.
