digger I just re-read the post you made about Chris King and I don't know what numbers you are getting. I went to the CK website the DropSet is $176 and all of their cupped headsets are $207 granted yes that would be USD but it still gets nowhere near any of the prices you are quoting. The only headsets from CK that would get up that high is maybe an old Titanium cupped Nothreadset or something super rare limited edition they no longer make. A Cane Creek 40 series would be about $52.99 and a 110 series which are quite nice would be 143.99.
I would be curious how you got such heavily inflated numbers? Maybe it is a little bit more in Canada, but to get $100-200 more just seems a bit off.
