Thanks for the tip onto the Gossen DigiPro F. I'm pretty sure I've narrowed my choices down to the Sekonic L-408, L-308S, and the Gossen DigiPro F. Considering these are all in my budget, which one do you guys feel would be the best bang for the buck?

Also, as an engineer, I wouldn't mind coming up with a little light meter that accounts for reciprocity it actually wouldn't be too difficult, you could perform a curve-fitting analysis on each films reciprocity curve, and then use the function to interpolate and convert the metered readings through the function, and output the accounted-for exposure
