Trying to decide whether to stay or go?

I have been Symantec/Norton customer since the days of DOS.  I have been running NIS since I cannot remember when, but it seems that NIS it at the end of the line.  I am trying to decide when I should upgrade everything (4 PCs) or simply just find an alternative.  My concerns:

* Lack of long-term support for NIS-ESD-Def-22.5.2.15-EN.exe.  This forum has seen better days and more involvement from employee reps (not user gurus).

* Cost per seat.  I used to get NIS for about $10 USD/seat.  You buy an Amazon 3 seat download and simply reuse that license.  But there are no more NIS downloads.  (However, recently I did get $10 USD licenses by buying in Taiwan/Hong Kong where NIS is still being marketed and promoted for what amounts to $10 USD/seat.  But it was only one license per installation.  So, I could not stock up.  The normal renewal app is $30 USD/seat.

So, your opinions please.  Stick with the latest NIS?  If not, go where?  Thanks.
