If your hands are not steady and vision is poor, I would suggest buying
a cheap ebay cnc machine. You can drill holes, mill shapes, route-out
circuit board patterns, and even mount a resist-pen to the head and
draw resist patterns.
A cnc machine opens up an entire world of new possibilities and makes
eveything more complex. You can certain do alot more stuff, if you
have the patience to trouble shoot frequent problems on the machine,
and follow natural instinct to upgrade.
