All search engines have turned their intention from quantity to quality. It is better to have 1 backlink from a PR9 (higher authority) website than 1000000 from PR1(less authority) websites.
Do not buy a huge amount of backlinks with less quality because they will lead your website to Google penalty. Be serious about your website.
