I assume you're in the UK.
Go to http://www.wiggle.co.uk/hybrid-city-bikes/
Use price filters, read the reviews.
Seems like there is only one bike there that fits your requirements, and Raleigh has a decent reputation as a bike company.

It get's nearly 5 star reviews. I say go for it.
The viking looks pretty comparable though, it's got a front shock, which I think is totally unnecessary for a hybrid / commuter bike. Most 'good' front shocks cost almost as much or more than that entire bike.
