ISO Crochet needles

Hi there I am learning to crochet so I can crochet some small blankets and hats for charity. I have always wanted to learn to crochet and this is a great reason. I am looking for cheap crochet hooks in good condition will be using alot of DK and worsted weight yarn not sure if the makes a differnece in terms of sizes I will need.

I am in the UK so must be willing to ship here.

Thank you
