Hi Mack, welcome to the Alesis DMDrummer forum.
I checked out a few and settled on Addictive Drums. It's got a demo you can try with hi-hat, snare, kick and one crash I think just to get a feel.. I'm sure they all have demo products you can test out. Myself, I liked the look and sounds of AD.. I found it much easier to navigate, set up instruments, etc than the others, and I really like the graphics and just how the whole product appears. Depends on what you want to see.. the other VSTs often show an animated set from above.. to me they just kinda looked lame. AD has graphics showing the sets from the front, they look more realistic and not so "animated" or drawn, and I really like the sounds of their kits and some of the processed effects. Plus I bought it and future add ons when they had half price sales so it was affordable.
Oddly enough, after playing with Addictive for over a year and loving it, I went back to just the module and have finally begun delving into the FX and layering in more detail and am producing some pretty neat sounding kits so I've rekindled my love of the DM10 module.. it still could use a few more tom sets, hi-hats and rides, of course. But yes, in Addictive Drums, I can't speak for the others, you select the Alesis DM10 preset mapping and it finds all of the toms (if there's anything that you have that doesn't show up..ie the extra crash which I also did when I got my Pro X, you simply use the learn function in the mapping settings and then those triggers are availaible in all the kits you load up to play). I'm sure that EZD would have the same setup.
