<human>: Give me the gist of the text in a nutshell

Some info on my boyfriend: he's 34, big time gamer geek, loves movies, video games obviously, technology, sci-fi, car repair shows, reading, and collecting a ton of stupid junk that collects dust and drives me crazy. It's hard to shop for him though because anytime he comes across something he likes, he just buys it. I was thinking of getting him a replica spaceship of Serenity from Firefly, but I haven't come across one yet. My budget doesn't allow for me to go all out either. I wanted to buy him the Lego Millenium Falcon, but I don't think I'm going to be able to afford it. So my budget is less than $100. If anybody can offer me some ideas, I'd be so grateful!
<bot>: Need X-mas gift ideas for boyfriend under $100 and preferably something to do with video games, sci-fi stuff, or replicas of something from a cool movie or game.
