If you are buying from eBay there are loads to choose from. Trouble is all the good prices are often refurb washers with a very short warranty. 1-3 mths.
However, I managed to find one that came with a 1yr warranty and the guy that dealt with these refurbs lived only 10miles away. I met him, and he was a real nice bloke. He sold me a unit that had been returned because a lady had cross threaded the valve that the hose attaches to. It had never been used, it was still brand new.
He simply replaced the valve and I bought a 3.15 for £80 with 1yr warranty.
One bit of advice is try to keep said valve well lubed. It's so easy to cross thread the plastic threads on the machine when attaching the hose.
