Thanks for asking. I'll be watching the replies. I have the 820 and have been wondering the same thing.

I have a Pfaff Expressions with the IDT foot and love it! Had there been a Janome dealer in my part of the country, I'd have another Janome, because the dealer I where I purchased my Pfaff sold out and left a couple of years after I bought my machine. :( My all-time favorite machine is still my Memory Craft 6000, but it needs a really good servicing.

My Bernina 830 came with a walking foot attachment, otherwise, I don't think I could affod it on a whim.
