Best tool to look for **************** niche sites

Hello there,
I would like to know what is the BEST tool to look for **************** niche websites where I can leave my comments or create profiles on websites related to my niche. Sorry for this post but you guys are using so many tools that I a little confused!

Basically, I am looking for a tool where I can type my keywords and the software gives me ****************, high pagernak blog/web 2.0 websites where I can leave my comments and create backlinks (i am not looking for a tool to spam the Internet to death)

BY THE WAY, is it true that if I create a profile with backlinks on a website which is NOT related to my niche, Google will discard it or at least will count it less?
thanks to everyone who will reply to me

comment kahuna, do follow blog finder are also great tolls to get related blog for commenting.

scrape box should do the trick

thanks for your reply! at last someone niticed me! i also read that fast blog finder is good...what do you guys think? but does scrapebox find **************** blogs? by the way...is there any way to get a free application? the one you told me are not free..

Something you'll learn about the IM niche very quickly, nearly nothing is free, everything requires at least a opt-in to get a download, if you do get your hands on a free application, I doubt it's anywhere near as powerful as scrapebox.

The best tool, in my opinion, is your own pair of eyes.

Examine the backlink profiles of other spammers.

After you've been doing it for a while, you become really fast. For example, you find one page which is d0follow, unmoderated and PR5 by following a spammer. You then do a site: search on the domain to find other pages on which you can comment on that site, and list the pages in order of PR using seoquake. Use these other high PR pages to get links to your other websites.

I can verify with 100% certainty that links from non-relevant sources are still recognized by Google. This is because I have ranked numerous sites using only non relevant links.

The confusion comes when people think related links are necessary - they are not necessary, but they are extremely helpful if you can get them.

Thanks for clarifying this Micallef...i needed your reassurances!
I knew the "follow spammers" trick but I would ike to avoid this. I have some free time during the day and I would like to do some do follow searches by myself. Since I have got this free time I would like to look for **************** websites related to my niche.
My blog is a tech blog, by the way which as far as i know it is a still tough in terms of finding related blogs...do you have any advise for me?

The more I go on with my quest the more I think that "fast blog finder" is the real winner here...do you agree?

thanks
