Headset type on CBoardman

[Jon2]

I'm currently building myself a road bike with a 2010 CBoardman Team Carbon frame. I'm trying to keep costs down at least a bit, and i was hoping to use a standard fork rather than tapered. I've found that there are a few headsets that allow me to do that, but i'm sure if they're the right type.
So my question is, what kind of headset does my frame require?
After looking at it, i think it's an integrated one, i it is, are all integrated headsets the same (apart from steerer size) or are there other things i need to consider?
If it helps, a complete bike for sale says it uses a FSA Orbit 1.1/8 - 1.5 Aheadset.
Thanks
Jon

As you know this is a minefield. To be sure the dimensions are not proprietary, if I were you I would try measuring the frame and compare with Cane Creek's info here http://www.canecreek.com/manuals/Headset_Identification_and_SpecificationGuide.pdf

Fsa's catalogue might also help you, if you have not seen it: http://www.bikemongrel.com/site/uploads/08headsets&accesW.pdf

If everything is standard traditional the simplest/cheapest solution is likely a head tube reducer. Both fsa and wheel manufacturing make them.
