I like it. A lot.
De = the ccTld for Germany, known as Deutschland by Germans and other German speakers.
I've noticed from the interest I've received in my own domains listed for sale, as well as from looking at recent and historical sales of .de domains and German language .coms that Germans seem to like a dash in their domain names. At least they don't seem to discount for them as heavily as other domainers seem to.
Here's one example:
http://namebio.com/info/hotels-deutschland.com Hotels-Deutschland.com sold for 2,369USD at sedo in April of this year.
According to
http://www.internetworldstats.com/top20.htm , Germany is the 5th largest base of internet users with 52Million+ users, which means that 63% of the population is using the internet. This is a lot of users, as well as provides a lot of room for future growth.
I would list it at Sedo, and get a featured listing for visibility. Make sure you list it in the German language category and gambling category. I'm pretty new to this, but I would shoot for low to mid x,xxx USD or low x,xxx EUD for this one.
