I'm 'in the market' for a lendrum... I tried several different wheels at the spinning guild here and finally decided that it was between the double treadle schacht matchless or the double treadle folding lendrum...
The Schacht was super smooth treadling and overall 'very nice' the lendrum was almost
as smooth (when I went back to it it was hard to tell which was smoother) but the biggest thing for me was that it was a good 4" - 6" taller than the schacht, and that was the finall deciding factor... I still wondered if i was sure I wasn't being too hasty in deciding until I looked at the prices (just tonight infact)... at the woolery it was $565 for the 'full package' lendrum, opposed to $809 for the schacht and it's normal accessories
I decided that it wasn't $200+ smoother
and the fact that the lendrum is a little taller really does make a big difference to me.
I still haven't bought one though... if you get one before me, let me know how you like it!!
