Well, I have taken the plunge. Last summer I picked up a 80's vintage Bostomatic... 5000 lbs of beautiful 5-axis iron. I had planned on getting the original controls running, but realized that repairing the old components would be expensive.
Here is the lineup I have planned.
Mach3, Smoothstepper, Campbell Designs Breakout board, gecko 320's, Keling 7220 power supply.
Stay tuned... more to come.
