It has no any effect on the search engine. A hyphen is one characteristic of a inadequate quality domain name.

If you use the hyphen will be disadvantaged. Never forget that you can use it as a possible surfers. The search engine does not have any effect. Dash, poor quality is a feature of the domain name.

there may not be much difference from a seo point of view but if you manage to avoid hyphens, underscores and numbers, it makes it easier for visitors to remember

Hyphenated domains are bad, because you can not easily pronounce them to your friends, especially on phone dialogue and on Radio. However, if you must use one, you have to beware of TM. Cheers.

Hi. I don't think there can be a problem with that. As long as you do proper SEO, Google will love you and will surely rank any domain you have =)
