Thing is, too, it varies greatly by region. In the US, a Blizzard 1230 will easily go $75-100 without RAM, while in Europe, they'd consider that insane, and swap someone a few beers for one.
On the other hand, I can barely get $100 for an A3000, which in Europe, they'd jump on it at nearly twice that price.
Regional scarcity plays a huge role in pricing.
