I am going to chime in on this even though it seems to be getting a bit "toxic" in here...
I own the Riva as well as a Pro-vari. I am using the Riva with a lr atty, and it is as good as the Pro-vari as far as I am concerned. The ONLY benefit to the variable volt is that I can fine-tune it to a specific atty. I have to increase the voltage on higher ohm attys. Battery life is longer on the Provari of course, but other than that I am actually favoring the Riva. The size is more manageable and the flavor is just as good as long as I use a lr atty.
I will not let the Provari collect dust since I paid good money for it, but I use the Riva just as often. One other benefit to the Provari is battery replacement. No matter what happens in the legal realm, they can't outlaw a battery. Attys, I suppose, would be another story. That would have an effect on either unit, though...
