How much is this antique typewriter worth?

How much could I ask for an old Underwood typewriter?

• I own a sx-100 underwood typewriter. It´s in fine conditions, it works perfectly, every key, every function. Maybe a little worn-out letters from the brand name on the top but almost perfect. I want to sell it but I dont know if it´s worth the price... anyone? (excuse my english, I´m from Mexico)

• Answer:

  I hate to tell you this, but for the most part, manual typewriters are a dying breed. Most people use a computer and word processing programs these days as editing is so much easier than it is with white-out etc. If I were you, I would just put an ad on craigslist and see what it would fetch. But honestly, regardless of how good a condition it is in, I wouldn't expect to get much for this. (For what it is worth, your English is just fine. :))
