I got my bows and hardware plus the corner pieces, all NOS, from Dave Walker.
As for consitency...think about the surplus industry. Some dealers buy large lots, some buy small lots. Maybe one day, you bought a pallet of bows for cheap,,,but the next auction, they bid out real high. It all depends who is bidding. And it depends on the overhead to get the surplus back to your yard.
For me...in So Cal, Dave walker is close enough for me to drive and have a nice little 1.5 hour road trip and pick up the stuff too heavt to ship. Dave's pricing is better than most.
