You could be lucky though. I got my 8x10 set through an bankruptcy auctionsite. I paid $235,00 (€187,00) for a 8x10 Cambo with three backs, 300 mm lens, polaroid 8x10 holder, wide angle bags and then some all in a sturdy flightcase. It is possible but you need luck. You can also buy on e-bay a pinhole for roughly $200,00 if you don't feel like making your own.
