Do a search on google. Try a search for: [seo dash "no dash"]

From an SEO point of view i don't think it makes a real noticeable difference. Some people have reported success with dash.

Although if you know SEO, optimize your sites, and know how to generate traffic, it does not really make that big a difference - seo-wise.

From an appearance point of view, i prefer no dashes, i think sites with more than one dash can definitely look spammy. Also from a marketing point of view i would definetely go with no dash, will be easier to remember and to brand..
