I will work with the golf side of things, as it has come up throughout this thread. A company like Taylor,Ping, Callaway etc. Yes, you pay for the name, and you pay for the warranty, and the advertising. But, and this is a biggy in golf. With those clubs, you get a ton of R&d to try to make the game easier. Those clubs are designed to take terrible shots and make them half decent. There is legitimate science involved behind todays clubs and you pay for a lot of different things when you buy them. They are designed to make you hit the ball BETTER. When you buy knock offs, you buy something that LOOKS LIKE something that is designed to hit the ball better. Big difference there. I have always felt that these companies lead the industry and evrone else simply follows. There is demand in the golf market for quality, craftsmanship and "prestige" factor with these clubs. I think fly fishing to a degree is like that. I am not certain how much the difference in R&D is between Sage and Temple Fork, but I know that I have had both and I have enjoyed both.
When it comes to high end stuff, you always pay some for the name. I kind of figure 3 or 4 different people make a profit on your clubs,2 of which even before you see the gear. An example:
Set of Irons
Manufacture cost $250
Sell to distributor $350
Rep Price to retailer $400
Retail Price $575
There is a definite market for high end gear in all past times. If a manufacturer is able to cut a link out of the supply chain, then they can get their products to market cheaper. If they have to go through many distribution channels, there will be additional cost.
Some people honestly believe they will be better with that gear and some don't. There are enough different channels out there to get good deals and buy used and get the rod you want. If you believe Sage will help you cast better and you do cast better when you use it and you can afford it, go for it. If you prefer to buy 4 Temple Forks for the price of one Sage, go for that. At the end of the day...who cares, you got what you wanted and could afford.
