Excluding textbooks for classes, I bought this for ~$300 (several several years ago as a special treat)
Most of my collection is thrifted/bought from garage sales (for a quarter to a dollar usually) but I do have a handful of nicer ones.
It's amazing how rich and ancient China's literary history is. I should make more of an effort to get into Chinese writing, all I've read is Shi Naian's Water Margin which was great fun. Maybe Confucius' Analects would be a good place to start with the really old stuff.
