I've recently purchased a Hitachi 42PD5100 from Nexnix, together with the extended 3 year Hitachi Warranty. After not receiving my warranty I called to Nexnix who advised that Hitachi do not offer their extended warranty on the 5100 model. Seems Nexnix had been mis-informed by their sales person to what plasma was covered by this warranty. Nexnix, to their credit have refunded the cost of my warranty and are presently looking to provide a new warranty through another company. Has any other forum members purchased, through Nexnix, a Hitachi 42PD5000/5100 with the extended warranty? Have you been advised that the warranty is not valid? By the way the plasma is excellent. Highly recommended.
