Might I then recommend Joseph Hollo's Zebra libraries, Pads Heaven 1 & 2?
I'm a do-it-yourself guy, so although I check out lots of patch libraries and snag any freebies I come across, I've actually handed over cash for only 3 of them, 2 of which are the aforementioned Hollo collections. (The third was an Omnisphere library that was kind of disappointing, so I don't talk about it.)
Also be sure to check out the coming (in a couple weeks) free version of Synthmaster. Several of the add-on patch libraries offered for that synth are very good, such as Nori Ubukata's "Art Rock Basics", which replicates many classic synth and organ sounds of the 70's. You can sound like Yes and ELP for $15!
