Which Groupset?

Anyone know where I can get last years 5600??? 105 brakes? Can only found the new ones. By accident I got the new 105 pedals and don't like how 105 is wrote as much, mainly as it doesn't match.

I'd recommend an upgrade to full 5700 - I had 5600 and 5700 feels like an improvement and tidies your handlebars a bit. FD shifting is brilliant, RD is less mushy than 5600 but not quite as good as Apex.
