Help me out here my peeps, My sister in law gave me a $50 gift certificate to B&H for my birthday ... I've been sitting on this thing (quite literally actually since it's in my wallet) since March 1st and I have no idea what to buy. As far as the important stuff goes, that's all in my sig. I've also got a pretty junky tripod that I have no need to upgrade, some really good Lowepros that serve me well, 9 gigs worth of Compact flash good for approximately 1000 photos at a time. I've got a Rocket Blower, a Lens Pen, an extension tube, an umbrella I barely use, a Sekonic light meter, and more books than I know what to do with. So what do I do with this gift certificate? I can save it and use it towards a set of Pocket Wizards which is definitely on my "to get" list ... but that's too expensive to do right now and to be honest, unless business picks up significantly, might be too expensive to do until next year (and at that point, this gift certificate might be expired). Any cool things I should have that I don't? Obviously $50 isn't a lot, but there's gotta be a "must have" out there that I could use?
