Go for the Sekonic, I have the L 508 and I absolutely love it! The 608 is even better as you can calibrate it, the 508 has to be calibrated at the factory. So if you got one that was calibrated at 18% (like me) you were on easy street, of you got one that was at 12% you were SOL. That is why many people hated them when they first came out. I have to say, Sekonic did not respond very well to this critizism, but they fix it in the 608, if I could afford it I would go for it.
