Would you purchase a high pagerank (PR3-4) aged domain for $200 or so, and then SEO it? I'm looking to build a site around a lot of mini terms and a few main terms. My guess is, the domain with high pr will appear more established for search engines than buying a new domain, which I have found to take 4-5 months with white hat SEO strategies, i'm not looking to blackhat this. And with google's algorithm change, i'm sure this will help, because my site content is unique, and backlinks are quality. What are your thoughts?
