Well, Let me put it this way: get rid of the scamming buisness model, sell people the rig for a flat fee w/ all future updates, and you probably shouldn't be selling this thing to people who are smart enough to go here: http://www.vmcomix.blogspot.com/ and get a rig that's actually decent for free. There's too many free options for you to charge people money.
