I'm about to purchase Xrumer. However I wanted to know firsthand from people's experience if it's worth it? I know for instance a few months ago there was something known as PmBlaster (Which seemed to have dissapeared). Which was cheaper alternative to xrumer and supposedely more effective. Are there any other alternatives to Xrumer which are more effective? What sort of traffic increases can once expect in terms of quantity and unique visits per day?
