one of my personal requirements for a mill was NO CAST PARTS. The country living mill had cast parts. I wanted to know that if it broke and if the company went out of business, I could easily weld a needed repair or have a machine shop make a new part.

They are expensive, but if you use it forever and it lasts that long, its not too bad. If you buy it, try it a couple times and pack it away, it would be very expensive.
