Me too Ron, I'm half thinking about getting one just to see how well it works. I looked at some reviews on Amazon which were all very positive apart from 1 review.
The only thing that I'm suspicious about is how accurate your machine heads are as in, when they are new they will have a smooth motion but when they get older "sticky" bits tend to develop. I guess they may have taken that into consideration but the proof would be in the pudding, as they say.
(PS Still working on the lapsteel, unfortunately the last few years have been a bit traumatic and I've found it difficult to find the spare time to really put into this, but once I've built my new speaker cabinets

I'll be getting back to it. Are you still working on the pedal steels?)
