Best way to blow fifty bucks

So I got $50 from my in-laws for my b-day. I'm just trying to decide how to spend it. I'm leaning toward a 6" smoked windshield for my up and coming fairing. I've already got Kury grips (and hate them) so I might buy a different set of grips. Maybe a throttle lock. So I'll put it out to a few of you guys, what was the best $50 you've ever spent.......oh and lets make it to items you have put on your Nomads.
