Well I for one just sent my A3000 out with UPS to Canada today. Why, well to get a Pegasos II after using one for the first time a few weeks ago. I let my A3000 with 200MHZ CSPPC/060 and mediator in a Mirage Tower go for a mere $800 and in return I ordered a new Tower case, 512MBDDR RAM, 120GB hard drive, Radeon 7000 AGP card, a 32X CD-RW drive, and a Peg II G4. Not bad at all!!!
So yes, I think with the number of people selling off the classics systems they are done for. I hated selling mine, but its time to move on I felt.
