You probably already ordered something. But I've used the QUp, and moved to the Little Fwend. Both work. But, the QUp is fiddly and you have to adjust it often. The Little Fwend is expensive, but it sure looks the part. And, I adjust it about once every month or two. It has worked well for 2 years, with only an occasional adjustment.
Tonearm lift
Does anyone out there know of a good tonearm lift that would work with a straight arm linear tracker like the ET ?
