Ideas for him

My husband's birthday is coming up and I still haven't figured out what to get him. He'll actually be gone on his birthday so we're going to celebrate when he is home. I'd like to find something specific that he likes but nothing has stood out. I want personalized birthday gifts for him so he knows that I put a lot of thought into them. I have a few ideas but nothing that shouts "Wow! He would love that!" That's what I'm looking for this year. That was his reaction to his last big Christmas present and I loved it. Hopefully here soon I can find some things that will really surprise him because that's my favorite part of birthdays!!
