Every brewer loves free hops. For my birthday a friend went through the stock at the LHBS and picked up an ounce of 6 or 7 different varieties of leaf hops. At a couple bucks an ounce it was a nice inexpensive gift. The cool thing for me was that I got hops that I normally use, as well as hops that I've never even tried before. Just a thought.
If you need to go cheaper than that, get him a cheap bottle of vodka for filling up the airlocks.
