Prof, I took the plunge in 83. Was best thing to do at the time as i was on call 27/7 helping to care fo my grand father. Would have lost a regular job doing so.
It's been good and bad. Most years its been better money wise. The hours SUCK. Your right, one machine leads to other needs $$$ tooling and suport machines. It's a fine line between "self employed and unemployed". If i wasnt so old i would go get a regular job and let some one else have all the head aches and worries.
