The $20 to $30 range is an excellent starting point. Darts are normally of pretty good quality at that price point, and going much higher will likely not benefit a beginning player much. Buying darts over that price range, on the other hand, may be appropriate in some cases for more experienced players. There are some great-quality sets available for less than $100. In general, a set of three darts will cost around $60 to $80, while four or five would be about $100 to $120 or more. Some sets include bottles of oil, others don't; some have wooden handles, others don't. Look for sets that are high quality without being overly expensive. Avoid sets with plastic or metal components unless you know how to treat them properly to avoid damage to your furniture. There are many factors to consider when buying darts. Price should be just one of them. You also need to look at quality, balance, number of feathers, weight, handle type, and so on. Good darters can make the difference between winning and losing matches, so make sure you get one that feels right. Handles should be comfortable to hold, but not so soft that they feel like playing tennis with them. The set should come with instructions on how to use it, and how to clean it too. Most sets also include some kind of bottle of oil for cleaning the dart board and darts themselves. Have fun!
