Here are some pics and a brief review of Revenge of the Fallen Infiltration Soundwave, which comes with a redeco of Bumblebee as part of the N.E.S.T. Battle Pack, priced at about $25

The Soundwave is black.........................not.
In case you missed it, Infiltration Soundwave is NOT black, contrary to the mislabling it was given by TFormers.com.
This Soundwave is more of a light, dull, cobalt blue.
He also has brick red plastic, and his satellite panels are black plastic. He has a red fade on his arms, yellow fire detail on his chest, a silver face, silver Decepticon emblem, and, oddly, a light orange (almost "peach" color) on the panel below his chin and painted on his legs. He also has dark red translucent plastic. The Ravage missile is dark grey plastic.
Infiltration Soundwave is, in my opinion, second only to Black Soundwave in terms of deco. He's definitely much better than the dull gray original release Soundwave, and I like his colors better than G1 Colors Soundwave from the "Gathering at the Nemesis" set.
The only thing I don't like about his deco is that weird orange paint. Some people might have a problem with the "flame" design on his chest, but I like it. I also like how the Decepticon emblem looks like a lapel pin, making Soundwave a Boss Pimp.
Alternate Modes (Satellite/Space Cruiser) 
Infiltration Soundwave has the most colorful alt. modes of the four Soundwave decos. He's still primarily blue, with red translucent plastic that mimics the glowing red portions that Soundwave had in the movie (and a red visor on his alt. mode "head" which is accurate). He also has silver paint on his satellite panels, with a red fade on the ends that is supposed to mimic them glowing as he goes through Earth's atmosphere.
Overall, I think Infiltration Soundwave is the best choice of a Soundwave for people who don't like the weak original deco and don't want to spend $100+ for Black Soundwave or $50 for G1 Colors Soundwave. At $25, the N.E.S.T. Battle Pack is worth the price just to get this Soundwave (not to mention an offer for an exclusive Ravage redeco, and a Bumblebee repaint). Infiltration Soundwave is, in my opinion, the best deco next to Black Soundwave. The colors really look great, even better in person than the pics might show.
If you have yet to pick up an RotF Soundwave, or aren't happy with one you might have now, definitely check Infiltration Soundwave out. He's pretty cool!
