I just purchased the Juki TL-2200 QVP Mini a few months ago from an authorized dealer and it came with several feet including the two you mentioned. Unfortunately, I don't know the answer to your question but I am curious myself what others who have the TL-2200 QVP Mini (or it's predecessor the TL-2010Q) have discovered. I'm aware of the Echo Foot and the Ruler Foot both of which are optional and available from Juki for $49 (i think). Would be nice to know if there are other generic high shank feet that are known to work well. Will be following your thread to see!
I hope you're enjoying your new Juki as much as I am - it sure is a fun, fun, fun machine!
