The Tsunami is definitely the cat's whiskers as far as decoders go. I see they have a drop-in for Athearn Genesis units now, but as Woody pointed out, there's no non-turbo EMD 645 yet.
I have one of the MRC drop-ins for an Atlas S2, and it's not bad. I haven't played with it a lot, but my only criticism so far is that the sound is a bit tinny... but I think baffling the speaker will help that.
I've done many Tsunami installs, but mostly steam. If you've ever done a standard decoder install, it's not bad - the trick is not just making room for the speaker, but giving the speaker an enclosure large enough that you get decent volume from as broad a frequency range as possible.
