http://www.halesowencycles.co.uk/road.htm have a Giro 400 for £419, and are up near Brum, which is closer than Cumbria at least ...
http://www.langsettcycles.co.uk/products.php?show=278 at Sheffield are £450
A bunch of shops seem to share a web content server, so they're all identical layout, info and price. Despite the alleged free market every one sells them for £500 RRP oddly enough :-|
Working through the list of dealers on the Dawes site most dont have web pages, on most that do the links fail, and the local ones I know of/have been to dont inspire me. (Global Esprit at Earlsfield especially, thieving bunch of b'stards who dont grasp the concept of warranties, service etc ...) Doesnt fill me with confidence about the product even though at £400 it's a cracking spec.
Think I'll just toss a coin ...
