I also have a Tin Lizzie 18, and now that I have learned to work with it (Tension), it is great. Mine sits on a gracie frame, and I find it very sturdy and not a problem. The encoders and rails were a problem to start, but since my dealer put on new everything, it works really well. The new Tin Lizzies are even better, and the price is so much better than others I have looked at.
