But also consider this: Google's aging filter makes it difficult to launch a new site. The aging filter will sandbox or quarantine a new site for a number of months, I've heard anything from five to nine. So that means that until Google finally releases your site into the general index, you'll get no search engine traffic unless you buy it.

So, while a PR2 isn't great, it's not bad really, you need a lot of history and links to move into the PR4 and above range. And if you're buying a site with a PR2, then it's already in the index. And you say that it's showing in Google isn't great, but with some massaging it could be and at least you won't have to wait out the quarantine period.

Finally, if this is the niche of yours that I'm thinking of, your existing sites are already at a PR3, so linking them to the PR2 site will like jump it up to a PR3 in a relatively short period of time.

I wouldn't worry a whole lot about DMOZ. Yes, SEO experts say it's important to get in there. I've been trying for two years and I gave up. It still didn't prevent me from capturing all the number one's I wanted.
