I agree - you need to set the rules at the start. Account for everything that may be required. Also, take in to consideration the fact that stuff is a hell of a lot cheaper in the US then here, especially as the exchange rate of £-$ is so good (for importing).
Should be interesting. Maybe we should set a various set of tests that cover temperature, size, sound level etc? As just doing temperature I know the "Yanks" will win
