I did it!
 

After a QB member suggested I try trading in my Bernina Stitch Regulator at the store where I bought my Bernina. I checked it out this week. I was able to trade in the BSR towards the embroidery module for my 640. I said I'd never get one but I want to do nice quilt labels for myself & clients. Store even had a used module I was able to get. It was a sign from heaven right? I won't get to take a class til sometime after middle of February as I have client quilts and am going to DD in CA to quilt and knit for 10 days. The BSR has been laying in a drawer for 3 years. I'd never used it as I bought the APQS Millenium long arm about the same time as Bernina. THANKS QB MEMBER FOR SUGGESTION!!!

Sweet! I love it when a plan works out. I love my embroidery unit. Have fun!
