Buying Google Adwords is very effective and can be done quite cost effectively if you target relevant phrases with a lower CPC and use geo-targetting (if relevant). The CTR will be lower, but these clicks are often better targeted rather than some of the high CPC and high CTR phrases.
The Overture PPC is now replaced with "Site Match" which seems (IMO) to be an expensive chocolate teapot. Only 2 CPC prices $.15 and $.30 plus a charge for each URL included.

Do bear in mind PPC campaigns can easily be self defeating if you are in a competitive market with a low profit margin per item, and you target the higher CPC terms but on the other hand hit the right terms and results can be excellent and very useful while you are waiting for "natural" results.
