Dell offers an excellent warranty. Better than almost all of the competition. Not only does the M209X come with a two year parts and labor warranty, but they offer an overnight replacement program for both years. That's basically the same as Epson's warranty, and some Mitsubishis, but few others offer a replacement program.
In addition Dell offers an optional third year warranty (with replacement too), and if that isn't enough choice, Dell may be the only company, with an optional accident warranty. Drop it, drown it? It should be covered if you buy their Complete Care option.
