How Much Would You Spend On A Christmas Gift for Jesus?

I was trying to decide on what gun to give away for a raffle, and I started thinking about the prodigal son. I know God is giving a gift through me, but in my mind, I'm giving a gift to God. So if that's the case, if I were giving a gift to him directly, would I give him the best I have, or would I cheap out and give him the minimum 10%? What would you do?
