I don't get it!
I do not see the, talked about, frenzy?
The A1000 is way much more computing history than the A500 is. Unlike the A500, A600 or the A1200 I don't see anything odd with an A1000 going for something a bit above €100. It is the very first Amiga, and it isn't the most common piece of hardware to stumble across. I, for one, haven't seen one IRL in my entire life.
To be able to find hardware second hand for bargains, isn't always the same as the hardware not being worth something in reality. I think paying more than €20 for a standard A500 is insane, but still I see them sell for almost €100 at times. That is frenzy, because the hardware isn't worth that much. If I find an A500 at a flea market, for €15, I don't find it cheap, I find it reasonable. But it I were to find an A1000 for anything less than $50, I would consider that insanely cheap. A true bargain.
Just my two cents.
