A 'The Sky is Falling' summation:
The community card shops have 'run out' of vintage material and local card shows don't have enough vintage tables to even accommodate the members of The Last Supper, and it continues to get worse as the 'refractorization' of the hobby continues unabated.
The only way there's ever going to be a hope of it changing is if the bottom falls out of the shiny market...but even that probably won't lead to more vintage appearing. We're sadly getting closer to an on-line (eBay, auction houses, etc.) or nothing environment for vintage collectors.
But try not to let it get you down.
