Nice flame bait.

You *could* learn about it.  I'm certainly no expert, and there are short
white-papers on Polyphaser's web site about the subject.  They aren't
written in jargon.

If you have mains connected to your gear, you have to worry.  In the last
ten years, the only thing I lost was an underprotected Sony TV.

If you are looking for some "rules of thumb" try these:
1) spend about 15% of the cost of your gear to protect it.
2) If doing it "right" the first time is difficult, do it incrementally,
most important parts first.
3) Don't do anything that'll make things worse.

That approach worked for me, but what do I know... I'm a mere Technician
with $10k+ in ham and monitoring gear, who wants to never have to send
his RX-340 back for repairs.
