Price range for a HP 41cx

[Sylvain Cote]

Sellers prices that only ship within USA is often (much) lower than sellers prices that do international shipping.
My experience as a international buyer from Canada, you should expect to pay around $250.00 USD with a plus/minus $50.00 range for a complete HP-41CX fullnut (calculator, manuals, box, pamphlets, etc) in great condition.
Of course, you can get one lower than that, but you have to very patient and lucky. Mint ones will normally sell at a higher price. YMMV
