I looked around at various machines, the PFAFF seems best for price. (in my price range)
It claims it has the largest throat space - space right of needle.
Right now I am using a Euro Pro Shark, nice machine but throat is small and tight, especially with the presser foot lever inside of that area.
The space on the PFAFF says 9 - 11 inches right of the needle - that is a lot of room.
