Seeing that the upgrade from K9 to K9U is $250, I'd say that's a great deal. I mean, you get not only the Rick and other bass VSTs, but Session Strings Pro, Session Horns, Alicia's Keys, all the Heavyocity stuff, the extra drums (I dig the Vintage Drummer), the cool fx like the verbs and comps ... to me it would be a no-brainer.
Cheers,
Eddie
