+1 Roddyrod, I have an RXP and RXT, both 4 stroke supercharged pwc's and they are unbelievable. I previously had 2 GTX 2 strokes those were very reliable as well. But the new sea doos are fast as shiat, quiet, and very reliable, I am in love with ours i would highly recommend them. They are cheaper then the GTX but the GTX's are more luxurious. The new high end gtx has on board navi!
