People making money on Agon or Ebay, i would say are quite a bit less then you would think,and fine if somebody doesn't do the research, like the guy you mentioned CJ Sono pre amp,now that should go for about 300,but if somebody pays close to 5, so what,it s a great pre at a good price from a great company,,but now a days, with the economy what it is deals and making money are harder and harder to find.
