Shimano compatible rear wheel

[Dominic]

I am currently watching a couple of back wheels on Ebay when I realised that if one was available I would much rather give some money to a club mate.

I am after a back wheel for TTing. As the title says it has to be Shimano compatible. It doesn't need to be flash, in fact it is better it's not, just true and reliable. To give you an idea, the front wheel is a Campag Vento. So not flash at all.

I am looking to pay between £30-£50 ( I am on a strict budget).

Anybody?
