Comparing IndexKings, IMtools, and other free indexers

I''m wondering if IndexKings is overkill, since it seems a lot of they create don't work and it takes like 2 days to run a single URL through it. Is it any better than the IMtools indexer, or any other link indexers out there?

Are you looking for free or paid tools?

For paid service/tools, you can look at the following:

Backlinks Indexer
GSA SEO Indexer
Nuclear Link Indexer
SEO Fast Indexer (Comes with SEO Link Robot or one off purchase)
Scrapebox Rapid indexer

Free Service/Tools for pinging/indexing:

BulkPing
PingFarm
Linklicious (Paid upgrades as well)
Nuclear Link Crawler (Paid upgrades as well)

Any of the above services/tools will do the job.
