Are all craiglist used ads scam?


Searching for used Krell 402e in Europe i found several on Craiglist for about half the normal price on audiogon and german audio-markt. In the past I have always found used obejcts on the craiglist normally much lower than expected.
Is this all scams??

Try HI FI SHARK as a litmus test to CL.
They surf most of the Euro listings .

As the prior posts indicate, if it seems too good to be true .... Walk away !

There is an irrefutable and inescapable tenet in this hobby: you get what you pay for .
If you stay local and deal personally with the buyer, check
the audio equipment if it's in a working condition..you will
avoid scams.

Oh, and make sure they have the original invoice.
