In the 3rd post of the linked thread, I wrote that I had just ordered Cabelas' waist high breathables. That was in the spring of 2012 and they are still holding up. No leaks.
+1 on Sierra Trading Post. Name brands at discount prices. It is one of the few online places that I shop. If you sign up for an account, you can get deeper discounts. Also, I find that if you leave your items in the shopping cart they will email coupons for free or 99 cent shipping.
