I have a mint pair of CS-33A's and I love them. They are perfect little bookshelf speakers for one of the smaller Pioneer receivers, i.e., the SX-450, 550, 650, 580, or 680. I think they sound fantastic as well. As far as the $100 goes, that would be a judgement call on your part. I think I paid $60 for mine, $30 on eBay and another $30 to ship. Can you listen to them first before buying? If so, let your ears decide for you, and if you like them, maybe you can talk them down on their price some. Just my $.02
