Gmail,Yahoo, Facebook, Twitter contacts importer in PHP

Question

Which is the greatest, cheapest application in PHP that I can buy to import Gmail, Yahoo, MSN, Facebook, Twitter contacts from my user's accounts if they wish to invite their friends?

I have gone through:

http://www.improsys.com/importer.htm http://www.octazen.com/demo.php and http://www.iplussoft.com/product/iplusinvite_pricing

Octazen looks awesome but wants excess of $320 for an all in solution. I don't want to spend that much.

All you PHP programmers out there you may have needed to build of integrate a similar app, I need to know which is the best PHP readymade app for this?

Any help would be appreciated and I'll smile with each answer - this should be your biggest incentive to find me something amazing :)
