Hi Scott
It depends on what type of VST instrument you are looking for.
If you want high quality sampled sounds then these links will give you an idea of what’s available. (There are many others)

If you’re looking for instrument emulations/synths then have a look at these. (Again there are many others)

There are also effects VSTs, however I suggest you get familiar with the use of VST instruments first.
Hope this helps
