LSI is a hot topic and you're bound to see some stuff for sale that probably isn't necessary to buy.Here's three different FREE LSI resources that in combination will greatly benefit your LSI resources and save you some money.
LSI Tuel:
You just go to www.tuelz.com and download the free versions of Tuelz.
I haven't set up individual downloads yet, so you'll need to download the entire package of free tuelz.
If you already own Tuelz, just be sure you do NOT over-write your full power tuelz with any of the free ones.
For those that already own Tuelz, just copy/paste LSI into your "main" Tuelz folder, and EXIT and restart Tuelz.
For more LSI research, you can check out:
http://www.quintura.com/
(which is included in the TuelBar)
And, I also like to use Google Sets for more LSI suggestions:

The LSI Tuel, Quintura and Google Sets are all FREE and together are comprehensive resources for all your LSI research.
-Boom boom boom boom.
