Well, the cardinal Western Flyer in that sale is on its way to me. Including delivery it was £101 or at today's horrendous exchange rate $152. Assuming the condition is OK, I'm happy with that as its around half of what I'd have paid buying new after I'd included $45 delivery and around £40 duty/VAT.
On the other hand, what yesterday did show was what good investments TB bags are compared to other brands. I bought the WF because it received relatively less attention than the backpack version or the larger bags, each of which went for a pretty hefty chunk of their retail prices. How many other brands could you say that of? Perhaps if, say a Red Ox ever came up on UK eBay it might do the same, but almost any other brand you could name (I won't embarrass any) wouldn't come close.
