Yep, longer-travel 1-1/8" forks are getting tougher to find; 20mm is still popular, but tapered is taking over the market. Come February, I'll be investing in one (likely a Sektor w/15mm, since I just bought a 15mm-compatible wheelset), and just roll that until the beloved Kona frame breaks. The Nixon I'm running now was bought in '07 ('05 model on clearance), and has been on 3 bikes now.
I get the reasoning behind the tapered headset/steerer, it's stronger and can take more abuse. I just mourn the passing of the old standard. (BUT, 1" went the same way.....)
