Tim... I would agree that for the money, ULS could have come up with something better. Or at least acknowledge the problem. Still, at the time I bought it (4 years ago) the fact that it worked at all was nothing short of miraculous. Sort of like the 3D printers for making patterns and prototypes.
I am looking forward to the company that can come up with a good servo driven laser. That would eliminate many of the problems with the ULS machines.
Regarding the Haas, I have also had very good luck with mine, with only minor problems with the tool changer. Their manual is one of the best I have seen for such a complex machine... oriented towards the average machinist. (which describes me!) With the look forward and HS machining, there is very little that I can't do with it. I also have the C axis table for it.
