I think it all comes down to whether you have more available time or more available money--and your particular skills. I've built most of my sites, but have bought about a dozen sites. Almost every one of those dozen sites was so misconfigured that I had to spend a substantial amount of time fixing problems and re-working the sites so that the search engines would give them serious consideration. There is also the issue of poor quality content and has to be re-written. I frequently spend almost as much time fixing a site that I purchase as I would if I had simply built the site from scratch.

I will continue to buy some sites, but only when the domain name is good, the price is right and the site is not loaded with useless duplicate content.
