I've had the $500 Outcast for 5 years or so and with a few minor issues, it's well built and designed. Honestly, I can't see where the other $1000 goes for the PAC, but I'm guessing it's also a solid piece of equipment. I also have the Outcast float tube and it's also very nice, so I'm guessing it's a theme with the rest of their product line.
First upgrade should be adding locktite to the screws on the oarlocks. Trust me.
