[R-390] Cutting power cords

[kurt]

I would like to stir the pot and ask a question that I have not seen covered 
here before. What are your opinions on cutting  the power cords off of 
equipment before it is sold off as surplus. Is this simply a quick and dirty 
way to render inoperative or an indication that the device truly does not 
work? The reason for asking is that I'm looking at some surplus stuff (390 
related) it is strictly what you see is what you get and the price is too 
high to gamble.
Thanks for your and consideration,

Kurt Holbrook
