US/UK/Aussie sale of goods legislation all comes from the same roots in English common law and as such should be relatively similar in all three countries (though of course the US may diverge a little more due to the longer period of seperation between the US/UK legal systems). Here in Australia, it is the right of the customer AT HIS OPTION to choose between a repair/replacement/refund of his money if he purchases faulty goods. I suggest you check the US Sale of Goods act or whatever it's called there (probably something similar) and perhaps contact your consumer protection organisation. Also, if you're still having hassles, many people find contacting prominent IT publications/newspapers has the effect they're looking for...companies hate bad press. It's an expensive machine, don't settle for anything less than top notch customer service (you paid for it!)!
