I have not looked at the Hardinge web site in a while, but it use to have
good info
on collets. I believe it said that there collets would be only accurate
for 1000
cycles. This makes me wonder if used Hardinge's collets (or any collets)
are no
better then imports.

Even if you don't buy the Hardinge collets, download and read their
workholding manuals, lot of useful tutorial information I have not seen
elsewhere.
