The KnitPick Options Needles http://www.knitpicks.com/needles/Needles_Options.aspx are wonderful as well as the Denise Interchangeables http://www.knitdenise.com/ . I like them both equally. It all depends on the projects & the type of yarn, etc.
Anyway, the only drawback to the KP set, if it really is a drawback, is the pouches for the needles is unmarked. So, I came up w/my own solution. What you think?
