Wedges to Buy

I am eyeing these wedges (photo below). I don't know which one I should buy, I really want them all but my budget is limited, so I think I should choose. Tell me guys what do you prefer to buy?

 I love this red color and the thread design in it from Christian Louboutin.

         

Also these wedges collection.. I have to choose between no. 2 and no. 7

And these wedges are all gorgeous, I want to have no. 3, no. 8 and no. 11
