Thanks for all the replies. I guess I'll try both the M6 and the Bessa R2 viewfinders before I decide on a purchase. It does seem a little strange though that given the high cost of the Leica, they haven't found a fix for this, even if it is not that troublesome to some. If Cosina can incorporate a viewfinder that apparently doesn't flare in a much cheaper priced camera, why can't Leica?
