Any of the Virus models are complete, the Snow is a little less beefy on a few specs than the Ti, but a good synth nonetheless. As far as being able to do the most of it, well, I personally like having a shitload of knobs to tweak and learn with. Surfing through menus (which will need to be done with the Snow, but you do get a software editor with it I think) is kind of a buzz kill for me. If its your first synth, VA or otherwise, you might want to look into a Virus C series used. It's alot less money and gives you many of the same core features of the Ti. Just my .o2.
