I purchased VV1 from IWIN. They are pretty good at helping when there is a problem. And if your dissaisfied for some reason they do what they can to fix it.
I lost my VV1 because my computer lost all my files for some unknown reason. So I repurchased it through spintop games.
And I purchased VV2 through Big Fish.
To be honest.I think that they all are about the same.
