Bryan,
Me - I'm going to be doing light milling, spot drilling and plasma all on the same machine
A number of yrs ago I made an MDF wood router as proof of concept and to see where the problematic areas were. It was a great exercise and I'm glad that I did it this way. Now the new machine is exactly what I needed and wanted.
But what plans do you have for using the machine, that pretty much dictates where rigidity, strength, etc are needed.
