Bookmarking Demon vs Outsourcing...AAARRGGHHH

Ok in a bit of a rut here. I used to outsource my bookmarking to the top sites + other smaller ones (pling sites or something like that) and im fine with those as I can generally get about 300 bookmarks done for $7

But then I look at Bookmarking Demon and wonder in the long run if I should get that and do it myself (and make the money back by bookmarking other peoples stuff for a fee)

So here is what im looking at and lets see how the veterans would go.

PROS to Bookmarking Demon to me.

Can use it anytime I have a new post or article done.
Submits automatically to the sites
Can use numerous profiles (from what I saw)

CONS to Bookmarking Demon to me.
Time signing up to each and every site they have (if i read right I need my own account set up for each)
If using diffrent profiles thats more sign ups (im guessing)

PROS to outsourcing the bookmarks.
Done in about 24-48 hours
$7 and done so no need to wory

CONS to outsourcing the bookmarks
$7 a pop and if done weekly or monthly can add up

So what do you think is best for bookmarking new post, articles, videos etc that I will be doing on my site.

Thanx
