Hypothetically: If you were offered a good product to resell, made by a reputable manufacturer, would you feel obliged to check if they ripped of the design? I don't think so. But maybe there are cultural differences :-)
BTW, there is such a thing as 'no dealer bashing' on this and other forums.
But I understand Pete's frustration; I would feel the same way.
However, before we all raise a shitstorm here, Pete should contact the guys and deal with them. From experience I know they're quite reasonable!
