What's a nice gift to buy for your husband's birthday?

I was researching on Drones as a potential gift idea. The man is interested in gadgets and I thought it will be a good and fun collection. Here are some links I found useful: http://sg.asia-city.com/tech/news/game-drones http://thehoneycombers.com/singapore/tech-hobbies-your-ultimate-guide-to-drones-in-singapore-from-the-best-models-to-laws-and-shops/#b9QjjvXhQdK3ZIMg.97 The second link also talks about the rules in Singapore on the use of drones. Have yet to decide on a model myself. Also makes for interesting activity to do with the children and get some cool videos for memory sake. :)
