Best SEO option for multiple domains

[PerryG]

I plan to purchase the following domains or similar domains, like these:

acupunctureFlorida.com
acupunctureLeeCounty.com
acupunctureFortMyers.com
acupunctureCapeCoral.com
acupunctureNapels.com

I want to get the most bang for my buck in regards to SEO with these great domain names but I don't want to manage multiple WordPress databases. I know I got install WordPress on one domain and have the others automatically forward to it. But I don't think that would be the best option. Or am I wrong?

So I am guessing I am asking is there a way to have one WordPress install and have all the domains utilize it. Meaning if acupunctureFlorida.com has the WordPress install and folks go to acupunctureLeeCounty.com they actually stay on acupunctureLeeCounty.com but utilize the WP installed on acupunctureFlorida.com.

Did that make sense?

And thanks for any help on this non-Studio Press question. I did some googling but didn't find what I am looking for.
