Men don't think the same way we do. If he asked you what you need, he wants to know what you need. Tell him what you would like to have. If he didn't care, he wouldn't ask. He wants you to have everything you need or want to be successful/happy with your hobby.
My husband asks this all the time. I don't try to second guess his motivation or meaning, I tell him what I want. If it is something we can afford right away I am told to go get it. If it is a larger purchase, he'll buy it for a special day - anniversary, birthday or Christmas.
