I created my business with a not common name. There was a .com for it. I have been trying to buy it for 14 years. The person wants over $1500 for it, when I believe its only worth maybe $200. I check every year to see if it fails to renews, but no such luck. And the site is just squatted - at one point just ads and now just a "please buy me!". So since then I use other domains, with the full business name or .biz etc. It still annoys me from time to time.
