RE: Prices?
Here's my thought, some people think that they need to spend more and that it gives them the illusion that they got better quality hardware and parts. It's commonly assumed when you spend more you get more. The question is will one set of hardware fly the plane any better than the other??? NO! I'd use toothpicks and duct tape if it worked. The difference from one plane to the other is always going to be what value people attach to the brand or name.
As for Carden.... Just saying the name could start a flame war.
