Favorite Link Building Tool?

Well first off I'm going to name a bunch of Link Building Tools...

SeNuke
Xrumer
LinkBuilder Pro
Evo II
LinxBoss
Traffic Geyser
Bookmarking Demon
Etc...

Forgive me if I got the names of any of these programs wrong, I am definitely not up to date on Link building Software. I actually run and manage an SEO Firm and we have teams of people who manage all of these different types of link building. Needless to say it takes a lot of time and a lot of hard work to manually produce services such as LinkWheels, High pr profile links and Social Bookmarks.

This is why I started thinking about LinkBuilding Programs. If I could setup a program to do what I've got teams of people doing I could cut costs substantially. I could offer a faster, more reliable service at a lower price.

Now the only program in the list that I've tried is LinkBuilder Pro and I dont mean to offend anyone but it was absolute rubbish. I had an email conversation with the creator and he actually told me to "Ask clickbank for a refund, I guess our program wont work on your machine". I'm running Windows XP with all the latest service packs. Why shouldnt that be compatible? He never even told me why it wouldnt work on my machine, just that it wouldnt.

I dont want any more experiences such as that one. I want to know which LinkBuilding tool you cannot live without. Which is your most prized and cherished gem.

I've heard good and bad about all of the programs above, but please give me your honest opinions. If you have never used these programs before than please dont leave opinions about them based on what your friend of a friend said about them.

I Look forward to a nice conversation about everyones favorite link automating tools.
