What has been the most you ever paid for a calculator?

[Monte Dalrymple]

In 1974 I bought an HP-45 for $395, shortly before the HP-65 was announced. I remember being devastated that there was now something better. But it's just as well, because tuition for one quarter at UC Berkeley was only $300 at the time, and I could barely afford the HP-45 as it was. I still have that machine, and it still works fine, although some of the keys are a little mushy.
