You get a 'free' re-ground drill bit, ground into an engraving bit,
with each spindle purchase. I have not tried it, but it looks like
you get what you pay for. He also sells reprints of an article about
how to grind engraving bits. I buy my engraving bits from
<http://www.thinktink.com/stack/volumes/voli/store/specs/mechetch.htm>
You won't find them surplus, like you do drill bits. They aren't used
in high volumes like drill bits are.
I can't say enough good about the above spindle, though. I have one
on my Taig mill, and it's what I use for engraving and drilling PCBs.
I don't think it would be good for milling metal, though.
