You don't need to look any further than my Film Effects plugins for Final Cut Pro. You can check out the free demo at www.nattress.com. You'll get the best tech support in the business and really enjoy them.
The Nattress filters ROCK! And cheap! Cutting 2 features right now, and using them on every shot. Also LOVE Digital Film Tool's 55mm filter set! Not cheap, but the Light plug-in alone is worth the cost.
