Actually just looking - ribble next day delivery on 105 is £41 they've said they can get 105 for £50, so for an extra £9 I'd probably just let them do it.
Although they do have to order the part in.
Other alternative is to go with Tiagra, which reading on line is basically the same as the 5600 series 105 I've got anyway. I think Tiagra might be the best bet.
