While its not a lite-weight company, if you want to know about customer service, Eureka! has replaced several broken tent parts free of charge years after I bought the tents. They once sent me a replacement pole at no charge with no questions asked. They did the same for replacing a rain fly for a huge four person tent. Regarding lite-weight, I have had great experiences with Henry Shire's Tarptents. I was shipped a tent body that had a bizarre stain (it only appeared in bright sunlight) on it that I was concerned may compromise the fabric in the future. He immediately sent me a new tent body and reduced the purchase price of the tent to compensate me for my troubles.
