Thank you! I so appreciate your reply... there are only so many times you can 'google' something like this. I have had my frame and janome for about a year and just have been using the 'speed control'.. which is ok... as long as you always go the same speed. I wonder why there are different 'versions'.. does it have to do with a cord? or the innards of the actual piece.. Thanks again and good luck! I found mine on craigslist.
