If you get any joy from Janome UK please can you post the information eg price and part number. I love my HP foot and would certainly buy the AcuFeed version too. Perhaps you can persuade Janome UK that there is demand.
I wonder how long it will be before Janome UK are able to supply me with this foot? I love the HP plate and foot and an AcuFeed HP2 sounds just what we need.
