What is the major difference in the PCI, RacerX and Rugged radio sytems? They seem to all look about the same but it seems you can buy the Rugged Radio stuff for about 70% the cost of like the PCI stuff. I was looking today and the PCI 4 seat with radio is 1675$ and the Rugged radio stuff is 1050. Both have the Carbon headsets but talking with Ruged it seems the promise theirs to have better sound and they have a digital voice processor so you don't have as much wind and other noise. I am pretty sold on them but thought I would ask and see what others thought!!!
