Turnkey Websites

[BlueGigs]

It doesn't really seem to me like there's much money to be made in turnkey websites unless you're knowledgeable about which domains to grab and how to put SEO techniques to work quickly. Still, there always seems to be a steady flow of buyers and sellers for this type of site, and I'm wondering if there can be a good payoff for the work involved. Does anyone here frequently buy/sell turnkey websites?
