Hmmm -- I was just cruising the 'Large Format' listings (don't ask) on ePrey and must have seen at least four or five Bronicas -- maybe they're disappearing into the wrong categories as the latest generation doesn't know what 'medium format' and 'large format' actually refer to??!!
I do recall getting quite a few e-mailings from KEH over the last couple of months. I seem to recall a recent one saying they had acquired a bunch of stuff and were in a bit of a bottleneck getting it sorted and posted. Maybe there's a bunch in a warehouse in Georgia. I do recall they were on buying missions at a couple of camera stores here in the Philadelphia area last fall.
