Brands to search for:

Tange Levin, Tange Alloy Levin, Campagnolo Record, Dura Ace.

Tange does both 27 JIS (for Bertelli frame) and 26.4 ISO/British;  Campagnolo, Gipiemme, Shimano Dura-Ace do only ISO sizes (as far as I know.) Hatta is an awesome brand but way too expensive.

I don’t relly like Chris King because of their horsey logo. I don’t like Velo-Orange hedsets, horsey shape and logo and too delicate, easy to scratch headsets.

How to install:

Use a threaded rod and two bolt and 2/4 washer, a vice and one wrench or just two wrenches. Job done. For just one bike doesn’t make sense to buy the Bearing Cup Press. 

To install the crown race on the fork, I use a pipe found at Home Depot with a soft big hammer and a pece of wood to place between the hammer and the pipe. It does work.
