Need Suggestions: What's the best software for link submission?

Hi Everyone,

I would like to know what is the BEST SOFTWARE FOR LINK SUBMISSION.
I have heard of Directory Submitter but a friend ( who has used it before ) said that it is not accurate
(ie sites listed under FREE are not actually all free or for PAID filter, sites are not actually all asking for a fee)
I need one that
-has an accurate database so it won't be a hassle for me.
-will also allow me to upload my own lists of sites.

Another thing, if I will opt to use Directory Submitter, is it easy to remove the sites not accurately listed on that category or filter?
Will it be easy to clean the lists? Can anyone give me more info on this please?

Lastly, I would like to know if there is a list out there of different link directories (directory submission list) that we can easily segregate with different filters
( ie FREE, PAID, MANAGEMENT niche, REAL ESTATE and the like.. )
If you can recommend a free one, it would really be great.

I really need more info on link submission softwares.
Any information you can give me will be greatly appreciated.

Thanks in advance.
:-)
