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

For sure it was my HP48SX in 1990 when I resumed my engineering studies. I dont remenber the exact price but it was something like ~ 400€, perhaps more :O

in 1982, I purchased a Casio FX602P for ~150€ to replace my FX502P. I was student and remenber i worked in the summer to have the money for it. So I remember _exactly_ the price : 990.Francs ;D

This two units works perfectly well so many years after
But the HP48SX is now much slower than it was in my memory ;D
