Help! Looking for 1st road bike

I am new to road cycling and looking to purchase my first road bike. I have a budget of £600, but need a little help on direction, do's dont's etc.
I have after a little research come up with a short(ish!) list of possibilities. Hoping that someone can help me eliminate a few from the list and maybe advise what i should be expecting for my budget.
Current list is;
Fuji Sportif 1.5
Specialised Allez
Boardman Road Race
Felt Z100
Felt Z95
Giant Defy 4
GT GTR 5
Cannondale CAAD8 2300
Cannondale Synapse 2300
Any advise on narrowing the list, direction, or even alternatives will be gratefully received!
Thanks

£600 secondhand can bag you a carbon Shimano 105 or equivalent bike with fair wheels at that budget (Aksiums, Fulcrums etc) and there is no reason why it shouldn't be in VGC.
£600 new does not get you anything like that spec.
Plus factor decent pedals and clothing into your purchase- they are as important as the bike.
If you do go second hand, which can be a minefield if you don't know anyone clued up, still think about getting a fitting if you plan to do a lot of riding.
Equally you can spend £200 on shoes and as much on pedals but this is clearly not essential or sensible.
