I've had excellent results with Harbor Freight drill bits -- US$5 (or $3 when 
on sale) for 20 assorted carbide bits in a case.  Check item #'s 44924 and 
34640 at www.harborfreight.com .  More than half are useful sizes for PC 
boards.

BTW, what does the term "knob-end" mean?  Should I guess it to be a derogatory 
term?

Cheers,
-Neil.
