I'm ready to spring for a noise-reduction package. I'm looking for comparisons of Noise Ninja vs. Neat Image (Pro versions). The prices seem to be similar (although you get both stand-alone and plug-in with Neat Image at the same cost as Plug-In only of NN). Is there some compelling reason to choose one or the other? I'm running CS4 in Win XP-pro (32 bit). Is there another vendor in the running I should be looking at (I don't want to spend much more than the $80 that these two run).
