It definitely only takes a few good links--or actually one link from a highly authoritative, trusted site.
Any links that I buy nowadays are links that lead to traffic--not just the "SEO value".
You can now buy Google Authorship. Is that going to be the next big thing? Same or better (worse) than a paid link? Perhaps.
