Homebrew PCBs

Thanks for the advice Chris and Robert. MicroMark often has a sale of 
one sort or another and for this week they are having a 15% off sale. So 
their 81631 drill press can be had for about $165. I'm leaning in that 
direction.

I inquired of MicroMark as to run out specifications for the 81631 as 
well as the variable speed drill press. Their response was not 
particularly definitive: "These machines do not have mfg. specifications 
on runout, but as an estimation I would expect the spindle of either 
drill press to have a runout in the neighborhood of 0.0015" or less. The 
chucks for both machines are standard duty drill chucks rated at 0.003" 
or less runout; chuck capacity is 1/64" to 1/4"."

I'm not well versed in drill press run out specs. Anyone know if those 
numbers are good, bad or otherwise for use in drilling PCB's?
