Road bike recommendations

I wouldn't have a £2k bike as my commuter unless I had somewhere absolutely secure to leave it in working hours.

Hmm maybe I can have just the one bike then? Something in my head says I shouldn't use a 2k bike to cycle to work on though, although it would make things much cheaper as I could just lift the 105 from my current bike on to the new one and treat myself to some new open pro wheels whilst I'm at it.
