CALLING ALL EXPERTS: Is there a backlink service that works?

Hello, I have been reading negative reviews about sites such as Link Juicer, etc.. I have also been studying sites such as Traffic Bug, My Link Club, and one I just stumbled upon a site called Social Adr.

I have read enough reviews to stay away from Link Juicer, but can anyone here recommend a good backlinking service that actually works? I know there is no "end all" or "all inclusive" solution, but I'm looking for such a service to compliment my seo services. I have some clients (white hat) that I have set up on monthly link building subscriptions and a service that works would simply save me some serious time.

Thanks in advance for useful replies!!!

I am trying MyLinkClub the second month. So far I can see promising results, but it might be too early for a serious review.

Why don't you try Xrumer + profile blacklinks. They are not blackhat and they really work in large quantities.

Thanks for the info guys. I use Xrumer services for part of my strategy, but need a type of "set and forget" service. I've seen Ross Goldberg's new link software, which does squidoo and digg i believe, which is a huge plus.
