I have no problems with half a garage of 70's and 80's bikes thansk to the internett. I recently re-built some 27" track wheels for less than $80 shipped (to AK). 27" stuff is getting harder to find (I don't even bother looking locally anymore), but if you are internet savvy, it should be no problem. Depending on what you have, swapping over to 700c in a pinch might be an option.
