Had a look on the Internet but I'm confused about the vast range in prices and therefore don't know how to choose an appropriate set. In shorty, I don't know how to grade/judge ER collects.

Thanks.
I can't recommand any specific seller but eBay is full of ER20.

BTW, I bought my spindle from the same seller as you did. After about two years it is still working well. Just make sure you connect the earth because the spindle is not earthed. Mine is just a 1.5kW air cooled, but I am still happy with it.
