I've got a brand new EAI (high zoot factor) 3/32" 16 tooth cog, if you're interested (I went 1/8th when I got my shiny new Record cranks, and never did use the 16 I'd bought). That'll give you a 71", which is right on the money for general tooling around...
Say $20?

Suzy
zoot factor? I have no zoot. Oh no! does it come in carbon fibre?
wots the 3/32 and 1/8th you mention?
