Oh and regarding the X6, I never found I needed a dremel with the latest X6 squared version...work perfectly straight out of the box, and a few additional hop ups made it perform better still. Tons of setup info and support available so no real issues with a new one of those either
The earlier (non squared) versions did need a fair bit of fettling from what I've been told though!
I will always have a soft spot for X factory...hard working small family business that punches well beyond it's financial means when compared to the competition!
