russ its not the tent, but the brand, Eureka, and the other standards like aluminum poles. The other point was that you can often save a lot of money through Sierra, but they are a closeout facilitiy. Campmor often has some very good deals on tents also and they do carry Eureka's, just not always on sale.
I've used a backpacker Timberlite on the river for a long time, and I can still replace a pole if needed. The Eureka Timberline is ageless, but not for everyone.
