Have passed this one on to the web sub-editors to be sorted. The two reviews seem the same, but prices and model numbers differ, and I'm just about to shoot off to the airport for a business trip, so haven't time to check out what has happened.
As far as I can see, the PDP-LX509D heading is the incorrect one, and the correct model number is the PDP-LX5090.
Sorry for any confusion - sure it'll be resolved very soon.
