Sorry to hear about your health problems, hope things improve.
Hindsight is a wonderful thing which in most cases comes to late to the party, in my case what started put as an exercise in producing a cnc small mill has ended up costing much more than the KX1 does now.
In may case I doubt if I would have started if Iknew how much it was going to cost but if you have the paying work for it then that is another ball game altogether! But as mine is only for hobby use and learning, the route I took certainly had more learning to it than a straight purchase would have been!
