Replying to Birthday Present For Dad - ideas?

Yoo

So my dad's 50th is coming up in a couple weeks and my brothers and I are looking for a gift for him. We want to change things up a little bit from the past years where we usually get him some sort of clothing for working out. Although he does like these gifts, we figure we should do something a little better for his 50th.

I'm looking for some creative and/or cool ideas. Let me know what you got?

+k for any ideas

P.S, money isn't too much of an object in this situation, seeing that there is three of us and my mom is willing to chip in if it's something worth it.
