Buying Advice

Hi,

I've just (slightly hurriedly) won an auction on ebay for a Siemens SN25M275 dishwasher. It's about three years old (apparently) - but I can't find any evidence of it through google or the siemens website (or on these forums). Is it my inability to function on a monday night that's hindering me? And more importantly, is this a sensible move at £82? Despite having won the auction, I'm sure it's not too late to find an excuse to wriggle out if it turns out I'm walking into a disaster...

Thanks in advance for any advice
