When I was faced with the same problem a few months ago, I went with a Cane Creek S-2.

It's on the 1" threadless fork on my rockhopper. Using a homebuilt press I was able to get the cups in the head tube with no problem. I had my LBS face the fork crown and install the crown race and install my star nut. Think they charged me all of $15, which was mostly for the facing. I assembled it at home after that, with no issues. Was actually surprised how easy it was to adjust in relation to a threaded headset. Now if I could just raise the stem without kludgy adapters or new forks...

Really like the headset though - cartrdige bearings, and is buttery smooth.
