Hi Grant.
I converted my NEQ6 pro with the Rowan kit. I was able to watch my good friend and telescope builder Len Clucas convert his. I am a total novice regards this sort of thing but even I was able to do it; slowly! It took me roughly a couple of days. The mount is quieter and smoother with improved pointing accuracy. My guiding graph on PHD is much flatter. It’s been installed for a couple of years now with no issues. Good luck. Tom Moran.
