Joe, unless cost is an overriding factor, I'd opt for the Digisix which is small and full-featured. B&H Photo sells them for $129.95 while MSRP is $199.95 I believe.

Karen is often to be found posting on the Leica Forum and the Russian Camera Forum.
BTW, I've just received a Gossen Luna-Pro (old model originally using mercury batteries) and it's HUGE. In typical German fashion it's built like a rock and I immagine it's about as difficult to destroy as a tank. After zeroing it, it agrees precisely with my Capital CdS meter.
