I have had several instances of nearby impulse damage and surge voltage 
on the AC line.  It could have been very expensive but for insurance.

I would put in a plug for either the ARRL or Ham Radio Insurance 
Associates equipment insurance.  HRIA will cover up to $5000 in losses 
for $136/yr including Mechanical Breakdown.  The two policies are very 
different so review them to decide which is best for you.

If you love your K Line as much as I do, you'll get it insured.
