Im not sure the current crop of headless tuners really are an improvement on the original Steinberger design, which is brilliantly simple, more like deliberate changes that are just different enough to be called "new". Does Ned still hold a patent on the original design? There are some Chinese knockoffs that look.a lot like the original bridge design called Overlords of Music, by all accounts a POS of the first order. The NS design clamping system is pretty ingenious, but hasnt been around long enough to say much about long term reliability, and Ned hasnt licensed it out to anyone else AFAIK.
