How about a used Oppo BDP83? Great machines, well built and fast in operation. Superb picture quality and the upsampling of DVDs for HD screens is really good too. The used price of these must be down around the figure you're looking at now (they were �500 new). AV Forums classifieds is a good place to look for one... or indeed any of a number of players, unless you want to buy new.
