What's your budget? Blichmann products are all really well made and there is something in every price range.
Last year we did a "Brewer for a Day" which I'm thinking of repeating because it was so much fun.I'm just wondering if anyone can think outside of the box and offer up any suggestions that they may have?
Give him a challenge. Give him a box with some random ingredients and a gift certificate to the LHBS or Northern Brewer and tell him to make a brew with what's in the box. Offer to be his assistant brewer for the day, too.
I'd be pleased with a sack of malt. Or a custom gold-plated tap handle.
