I have a Tin Lizzie 18LS which I love, no issues with the machine, but there have been with the encoders (skipped stitches) and stitch regulator(racing with tiny stitches). I think I have solved those problems myself, though it's taken a few years as no one near knew what the problems were. However, this was purchased quite a few years ago, so I imagine both attachments have been upgraded by now. You will also find quite a few other machines are actually re-branded TLs. I am also disappointed with my frame, as the seller created his own style, made from aluminium, and joins from when it was extended cause some bother. Am told steel tracks are better for ease of movement. Keep in mind that I do not live in the USA, so mechanics for the TL here are scarce as hen's teeth, but I have had prompt replies from the makers recently. I am also considering up-dating to a more modern set-up.
