Topaz Plug-Ins Part II

I am about 10 days into the 30 day trial of Topaz plug-ins.  I downloaded the free trial of the entire suite (14 elements).  Here are the plug-ins that I really like:

ReMask
Star Effects
ReStyle
Detail3
Adjust5
LensEffects
Simplify

So far I have purchased only Simplify.  I figure you can't go wrong for $20.  Of course, that sale was over February 28.  

The question is…do I spring for the entire suite of plug-ins offered to me for $344.99 since I purchased Simplify or do I wait for coupon codes and add plug-ins one by one until I get the ones I want?

This is a photo I found on the Topaz Labs website.  The photo was processed using the "Star Effects" filter.  Here is a link to other photos using that same filter:
