CONFUSED!!! Which new headset?

Nifkin

My winter commuter is a 2009 Specialized Crosstrail, and it needs a new headset. The OEM one is a 1 1/8" Specialized integrated, Campy style cartridge bearings, according to the bumph. Can anyone enlighten me which reasonably inexpensive (it's my 2nd bike, after all) headset would work as a replacement for this? I was looking at http://www.chainreactioncycles.com/fsa- ... -prod12760. If anybody knows what spec headset I'm after I'll be very grateful!

Cheers

I put one of these in my winter bike that's also 1 1/8" 45/45, same as the FSA but cheaper, it's just a Cane Creek re-badged headset.
