Why is using flash a bad idea? Sometimes you need fill-in to balance the exposure. I've been using a Mecablitz 34 CS-2 with the Bessas - its expensive, but very powerful for its compact size, covers out to 24mm with the difuser, and gives three auto apertures. It also has a built-in slave mode (stand included) and is designed to slave to digital compacts, as the slave can be set to ignore the initial flash, being triggered by the second (I haven't put that very well, but digicompacts usually flash at least twice even without red-eye reduction- the first flash sets the white balance, the second is used for the exposure.) Some people don't like the fact that it runs off CR2 batteries, but thats what gives it the power for its size - and my Bronica RF and Pentax SLR both use them, so I've always got spares (if my wife hasn't 'borrowed' them for her Pentax...)
