I'd like to also suggest the GOSSEN LUNA PRO SBC. I came kicking and screaming into modern times two years ago, when I bought the LUNA PRO. Before that I was quite proud to say that my camera bag did not have one thing in it that required batteries, and that included my Weston Master II meter.

The Luna Pro has become a trusted friend. It is a fantastic reflective/incedint meter by itself. It does have other options to expand it's value to the photographer. I use several attachments for it: the 1/5/10 degree spot meter, the microscope attachment,and the copy attachment.

You can find them on used eBay, and at most camera shops around the web.
