I have the Tin Lizzie 18LS and love her. No problems with the stitch regulater, but did have issues with skipping stitches, until I found out the encoders weren't heavy enough on the track and wouldn't turn. Being a 'bush mechanic' I fudged some changes, and all is well. I have an aluminium frame, but would rather have it on a table as opposed to the set-up I have now.
