100 Manual Directory Submission (PR3+) - Good or not?

Hey there guys, how's it going?

Basically, I'm pretty low on cash right now, and the only good deal I can find for SEO, is a 100 manual directory submission, onto PR 3+ directories.
I've seen positive results with posting my site to only 10 directories before, but I just wanted to get the approval of blackhatworld, because I wouldn't want to do anything harmful to my SEO...

What do you guys think?

Thanks SO much, everyone.

How much would you be paying for that?

They are auto approve directories and some directories take much time to approve ,so its dependent on the one you choose.Its better to go with low number and slowly increase it.

Dude i like directory submission. And always do this for my main sites.
Manual Directory submission is really cool for SEO. do over do. Monthly 100 Quality posting is enough. Don't just target the high PR one. You have to remember that the lower PR one are also good. Find do follow directories and of course select the exact category.
Go ahead.
