I've used Dfine 1.0 the Dfine 2.0 for years. 2.0 is especially good and effective reducing noise while protecting detail. I've also used Nik Sharpener for years, and after learning how to use it, really like Sharpener 2.0. Haven't upgraded to 3.0 yet. I tried Viveza -- wasn't impressed. I've also used Nik Color Efex Pro (1.0 and 2.0) for years. I like those as well, though don't use them as frequently as I once did. I also tried SilverEffects. Not bad, but I have Alien Skin Exposure 2, and I prefer that over SilverEffects. Overall, Nik produces very good, competent filters. If you're truly interested, simply download them and try them yourself. They all come with a 30-day trial, which should be more than long enough to see if they do the job.
