There's another decision: buy a dye based printer, or a pigment based printer.
If you think you'll live 200 years and want your prints to still outlast you, then buy a pigment based printer.
For a normal, human life span, a dye printer of the latest generation will be OK.
Most higher end Epson, for example, are now pigment based, but the Canon Pixma Pro 9000, for example, is a good dye printer, costs about half what its pigment ink counterpart costs.
Both types of ink will give you great results. It used to be that dye based printer had better colors, but in higher end printers that gap has been almost closed.
It used to be that dye prints faded quicker, but that gap has been narrowed. Canon's ChromaLife promises 100 years.
Both types of printers will give you a longer lasting print than a traditional photo.
One other tip: the best printer will not help you, if you buy low end inks at Walmart, Walgreens, Staples, etc... In this case you can sit down and watch your prints fade.
Again: don't underestimate ink quality. You have to be really, really knowledgeable to buy third party ink, and people who are that knowledgeable often buy the manufacturer's ink, as it's well tested.
Third: don't forget the paper you buy. There is a connection between printer, ink, and used paper. Some papers cannot be used for both kinds of inks.
