Depending on the brakes you've got (need long / extra long reach calipers) you can run 700c wheels on that (I've done this on two frames). A cheap pair of those + new brakes (sjs sell some very long reach calipers) may even be less than £80 if money is a big issue.
I have some long reach shimano calipers (59mm I think) which I used to do this and which worked for the first frame. The second needed the extra long reach ones from SJS.
I'll try to remember how much I paid for them but they can probably go for cheap if you need them (PM me).
