Without knowing what size hub its hard to say, but its probably 4 or 5 ports so I think its a little pricey m8.
Theres a kit here: <a href="http://www.netshop.co.uk/products.fwx?codep=ng105&clk=tx" target="_blank">http://www.netshop.co.uk/products.fwx?codep=ng105&clk=tx</a><br />Nearly £20.00 cheaper. I am sure you could find even cheaper.
But if you only want to link two PC's, you dont need a hub.<br />Just the network cards, and a crossover cable that plugs into the cards.
