jonathan18: A workmate was telling me the other week he bought a pair of Blackbox M10s for $20 at a charity shop here in PN; that's certainly a lot cheaper than I paid for mine! I'm assuming the shop had no idea what they were selling.
As far as non-tech stuff, I got my wife for her birthday a stunning six-setting Shelley tea set for under $130 from a s/h shop in Bulls last week - another seller in the town said that seller has no idea of the value of what he's selling (unlike the shop on the turn-off to Taupo - they have the opposite problem!).
Are you referring to that shop selling all the mega-pricey imported French antique stuff?
