nice domain for the European market due to the hyphen, but even the word internetbanking in German (which is where they love the hyphen domains) its one word, but depending on the traffic it receives I would say high $xxx to low $xxxx
Simon's advice is very much on-target. And hyphens don't hurt strong keywords.
I really don't know where you got that information.
In Germany a non hyphen domain will always be worth much more than a hyphen domain.
You see, in German combined words are normaly written together, and not two words, like in English. This kind of words will accept no hyphens. The exceptions, words that are not written together, that is where hyphens are sometimes accepted. In those cases, mostly both versions are taken and the version with Hyphens is used for SEO.
I didnt say hyphen domains are better or worth more, I said Germany is one of the few countries in which hyphen domains have a high value for the right domains, and like I said, this word would be better without hyphen because it is one word, but for domains that contain two or more actual words in german like day-and-night (tag-und-nacht) the hyphens are better. This domain would be really good developed into a price-comparison website for different online banking providers
