I have several onOne Photoshop and Lightroom actions/presets and they are decent for freebies. Personally, I wouldn't purchase any of their suites. They all (not just onOne) advertise those things as push button answers to photographic excellence, and 95% of the time it just doesn't work that way.
Invest in some good books on how to edit your photos, such as Scott Kelby's Photoshop series, and learn how to do it yourself. It will be money better spent.
