Converting a European style handpiece

Converting a European style handpiece slip joint to US standard

Hi, I would like to but the Foredom standard CC flexible shaft
machine, seems like a very sound buy, however all my hand pieces are
of the European slip joint connection style and will not fit. Foredom
does a European style shaft and sheaf however I have been quoted
$106 dollars and I wondered if there was some adapter to do the
job…does this exist? does anyone have experience with this problem?

Kind regards,
Brendan
