A good FREE people search?

Alright, well, one of the best things the internet has to offer (and always makes people think I'm a stalker when I tell them about it) is people search. It allows you to get in contact with lost friends and find people's phone numbers. The problem is, more and more often, their phone number is unlisted on all the free ones. For the most part, there are a lot that you have to pay for that claim to have everything from information on relatives and deaths in the family to previous addresses, and of course, phone numbers. Problem is, I don't want to pay for it, and I don't want to waste money if it ends up being a scam. What do I do? Has anybody out there found a good sight for people search?

zabasearch.com is probably what you're looking for. It might help to use it in conjunction with a site like privateeye.com, which gives you a list of someone's places of residence as well as possible family members. They charge for any further information, though.

Edit: Only applies to the U.S.

Well, I live in the U.S, not Argentina. I just like the name "La tierra del Fuego". It means the land of fire.

EDIT: Oh, silly me, I forgot which made up location I used. El Fin Del Mundo is in... Ecuador? It means the end of the world.

Either way, I guess that's the best I'm going to get. I don't really need it now, but I'll try it out the next time I do.

http://pipl.com/ is amazing.

Well, I guess that if a number's unlisted, a number's unlisted. You can't find it anywhere.

My company hasn't officially rolled this out yet but: http://www.findanything.com
I'm not sure how functional it is right now though, I'm not of the group that's building it.
