Im cycling a Giant that i got in that price range, cycling to work and the odd spin - its a grand bike, and a very common brand so most bike shops would have it. Where are you based?
Have just joined the bike to work scheme via my employer - I got a Specialized Sirrus Sport for around €300 net of the scheme. Also got all the required gear, helmet, clips and shoes etc etc at the same time so they were all covered under the scheme.
