Can anyone give me suggestions of a good, cheap (ebay....) batteryless light meter? I was getting ready to shoot my brother's surprise wedding yesterday (he surprised us, not the other way around), and as I pull out the 6x6 & gossen digi-six, I notice it's out of battery... And I'm 4-5 hours away from home (and the spare battery)!

Well, I managed to borrow someone's ae-1 and get a good guestimate on lighting, but I really need a back-up light meter. I'm wondering if anyone has any experience with Leningrads, Westons, anything else at all. New Sekonics etc. are out of the question, I don't want to spend more than 30 bucks (and that's stretching it). I just want a meter that will be precise on daytime-evening lighting... you know, a back-up.

Thanks in advance,
