sysop104, how much did you pay for it on ebay...
Did you know that if someone sells something that is knowingly substandard to you you can degrade their ebay rating, and claim £130 back from ebay as compensation.
You could always return it to the seller and demand a refund. It sounds like he didnt give you any of the manuals, as you were unaware of the hard reset function. More importantly - If he didnt pack it properly then its his fault. Did he use a registered postal service, was it signed for upon delivery, what was the condition of the packaging?
Unfortunately you get what you pay for these days, and given the complexity and fragility of this wonderful device, I opted for a new one under contract, I did toy with the idea of getting one on ebay though, having read this I'm glad I didnt.
