Wouldn't touch a clickbank product w/ a ten foot pole....
However, the blackhatter in me, sells the crap out of clickbank products to unsuspecting fools..no offense to those who bought this, but seriously - I'm only speaking candid here because, it's blackhatworld and I respect the community here - but if you're going to spend your hard earned cash..
You need to do it on either REAL quality automated software like Scrapebox, SENuke, AMR, SickSubmitter, BMD, etc... OR Use it to hire some people from Asia @ $1-2/hour to do tasks for you and build your web empire....
Guru's are really just people who got lucky, and somehow found 'fan-fare'.. some of them may have even stumbled upon a secret here or there, and used that to catapult them to stardom..

Most are just adequate self-promoters and BS'ers.
