I find that the throat space on my 440 is really small.

After reading all your comments I have decided to wait until Bernina (or someone else) comes out with a ruler foot that is safe to use on the 440 I've had my 440 for at least 8 years so I don't think it is under warranty any longer - but I certainly don't want to have to bring it in for repairs! Tartan put the scare into me with her statement that forgetting even once not to raise the foot while in needle down position will cause damage. Lol. I know myself - I would forget.

Thanks for all your comments/advice!
