Low light meter recommendations...

[JoeFriday]

I highly recommend the Luna Pro SBC.. I've got one and love it.. it's very sensitive and accurate.. and amazingly easy to use.. the only problem is the size.. a bit larger than a pack of cigarettes.. but it'll handle any lighting situation you'll encounter (other than flash photography)

I've also got a Digisix, which is very convenient.. accurate, but not as sensitive as the Luna Pro.. and takes longer to convert a reading to shutter/aperture combinations
