Graf von Faber-Castell makes some really nice inks. They might not be the brightest, most inspired colors, but if anything, they are well-behaved and they can be relied on.
Graf inks come in a beautiful, heavy glass bottle, appropriate for an ink that comes at a premium. 25 EUR/ 30 USD per bottle is a somewhat steep price, but they do contain 75ml, which is considerably more than most other brands.
