Looking for a cheap rear wheel (or set)...

BillB I have a pair of touring wheels, Mavic A319s in silver laced onto Harris Cyclery (Formula, system ex, etc delete as appropriate)fixed /fixed hubs in black with shiny DT double butted spokes. I built up a pair of open pros so these are currently going spare. Bad points are:

700x28 are the narrowest tyres you will get on them
they are a bit grubby but otherwise good condition, I'll probably clean them up before selling
they are not light (but very strong)
I want to sell the pair, not just one wheel.
I'm in Guildford not London, but I'm passing through London on saturday evening.

£75

EDIT: I have a Miche primato 32h single sided fixed hub too, brand new, £30

hmmm...
i'll keep it in mind. not sure it's what i'm looking for though.
28 sounds quite wide as a minimum and i don't really want to fork out for a whole wheelset at the moment unless it's exactly what i'm after.
hub on it's own would need to be 36 spoke.
i'll have a think though.
