Help me come up with a present for christmas..?

I need to get a present for my father-in-law. It has to be some different/unique since if it’s obvious and he wants it, he already has it. He loves drinking beer, wine & tails. He has a little bar-type room with tapped beer and margarita maker. He also enjoys grilling (but has a tonn of cookbooks already) He has a little cabin with a campfire, but I can’t think of anything to get for that either. I would like to get him something undr $50.. I just need something really neat and unique that he might like. It’s really hard to shop for people who already have everything!! Any suggestions will help.
