I have the Tin Lizzie 18 DLS and love her. I have her set up on a 12' frame. When I was shopping for one last winter, my DH did all the research and had narrowed it down to the Tin Lizzie or the APQS Lenni. He felt the Tin Lizzie was better built (no offense to the guys on here, but, definitely a man thing) and ran smoother, and more bang for your buck. She is all I will ever need...but the QBot would be nice.
