Hi,
Thanks for the replies.
I have decided to buy a kit from Parr's Rulers who promise me one of their foot and ruler kits will work on the Record 930.
A mat, foot and 2 x rulers comes out to £84 (inc postage) which is cheaper than the Bernina foot 72.
I thought it was worth a try as, presumably, if the foot is not compatible I can send it back and get a refund.
I'll let you know how it goes.
