Yes. I'd recommend the SEO press release from PRWEB.COM for $200. The company I work at now, uses it;

We've been syndicated across forbes: http://www.forbes.com/prnewswire/feeds/prnewswire/2007/08/07...

and yahoo: http://news.yahoo.com/s/prweb/20070823/bs_prweb/prweb548843_...

it's very effective, as you can see. It lead on to other things like industry coverage and free links - we've had numerous travel agents cover us on their blogs or podcasts and a Forbes web article actually printed because of our press releases.
