I'm around $500+ spent on this service, and still would recommend it.
I have been mainly using it to Tier links, however I have done a few anchor variation blasts to money sites as well.
The only thing I dislike is how the High PR d0foll0w links are $20, but often end up on pages with 300+ OBL, which IMO is pushing the limit nowadays.
(There's other bugs with these types of links too, some do not get posted... it can get annoying spending $20 and missing a lot of links).
Again, I recommend this service, but ONLY to those who understand the proper way to use it.
