Entertainment.eu sold for $2,500 and CorporateEntertainment.com sold for $14,000. Entertainment.pro would be a good name for a corporate entertainment or party planning site. The downside to Entertainment as a keyword is it's 13 letter length but you could argue that makes 2 word domains with entertainment in even less attractive. Entertainers like to be regarded as professionals, there are alot of them, and they are more likely to have a web site to promote themselves than most people. Reseller you'd probably be looking at $200-$300, but you should hang on to this and wait for a $X,XXX end user bid.
