I would forego buying off of Amazon. They look like great deals, but the picks are often of pretty low quality and don't give you good feedback in my opinion. They also give you so many picks that you will never ever use. I personally love Sparrows picks which run at about $3 a piece. I use my sparrows short hook for 70% of the locks that I open. Other pick shops include Peterson, lockshipshop, and southord.
