I did buy a demo Tin Lizzie 18LS, love the machine, but my regret is also buying the aluminium frame. Am told steel tracks are much better. I later bought an extension to 10ft and the join gives me problems, also the encoders have been one big headache.
A Pfaff CV embroidery/sewing machine, also a demo @ a very good price, and it has a large hoop. There are so many features that aren't explained in the manual, & I find it difficult to fathom - not user friendly - & I just couldn't spend the time needed in town getting lessons. It would take me all day to figure something out, & forgotten how to a week later. So it's been serviced and packed away.
Sometime I feel like selling the lot - Downsizing is big on my mind these days - when the days get cooler.
