Juki makes a high speed, high shank machine similiar to the Brother Pq1500' sorry dont know the model number, and their feet will work on the Pq1500 machine. I purchased a fmq foot from Allbrands that was listed as a upgrade fmq foot for Juki's, it works perfectly on my Brother Pq1500. It wasnt cheap but it was exactly what I was looking for. It would bet they have a walking foot too.
