new gear vs used gear

another thread got me thinking about this,how much of your current rig was bought new & how much of it was bought here on audiogon or ebay.

out of the 14 seperate pcs of gear im currently running 12 were bought on audiogon & 2 were bought at a dealer.

this isnt a dealer bashing thread i was just curious as to the numbers & why you choose to buy used or new.
