I know this is kind of a better anniversary gift, but it would work as a birthday gift too if you have been together for a little while.
Also.. you could make him a cake/cookies/cupcakes.. find out his favorite.. it would be realy cheap and thoughtful.
If he's an outdoorsy kind of guy, take him somewhere outdoors that he loves and have a picnic.
Cook him dinner
I can't think of anything else right now.. but I hope i helped.. good luck!
