I bought from him, too, with no issues or complaints. Fast shipping and good communication. I did not go to him for support, though...came to the (other) forum instead. (Didn't know about this one).
I would purchase from him again, however, I'm finally hearing some REAL reasons to go with Dax - for example, I understand he balances the flywheel for a smoother run, etc. Too bad he doesn't make those points on his terrible website - I would have paid more to purchase a better machine now that I understand more...but then again, his delayed shipping and fee to get it in a week edged me over to BGF in the end. It all worked out.
