@Mr Numbers:
If you're considering a road-bike then this will probably hit the mark:

Big-name manufacturer with big-name guarantees on frame & forks, both of which are good quality at this price. People love their Allez bikes, never heard a bad word about them
Edit:
There are some decent Scott bikes in your price-range too:

I have 2010 Scott Speedster S20 and it's a better bike that I am rider. They do a S50 in in that price-range, and an S50FB which is the same bike but with flat-bars.
HTH
