If you are looking for a 2hd one you might as well google hen's teeth or rocking horse manure.

https://www.sorotec.de/shop/Spindle-...-000-rpm-.html
https://www.prototools.co.uk/kress-m...dle-1050w.html

These are two suppliers that aren't actually flagging as out of stock.

https://www.sorotec.de/shop/Mafell-F...230V-50Hz.html this uses kress collets and is a little cheaper.
