Thanks... yes they're still working very well indeed. Same performance as in my post a month ago. I wouldn't hesitate to use them instead of rack and pinion on a 2.5m axis. You'll get better accuracy, longevity and it'll work out cheaper. With a RM2510 (or even a higher lead) the machine will be plenty fast enough with good acceleration.
They do look good, but as you say they wont be cheap.
