If you're not a Michelin PE2 snob, then in this month's EVO magazine, the Uniroyal Rainsport 2 came 2nd in a group test.
The PE2 came 5th (not much in it though).
Oh, and the Rainsport 2s are half the price you quote above. About £69.
Otherwise, try "My Tyres" which is just about the cheapest "VAT inc. delivered" place I know of for any tyre.
