Well of all Casio calculators I suspect the pinnacle was the FX-501P/502P and FX-601P/602P and these are definitely not cheap, snapped up on eBay pretty quickly, or bidding becomes high.

If the HP-41C/CV had a competitor other than the TI-58C/59 these probably would have made the grade, not sure of any other calculator of that period 1979-1982 that could also compete.

HP-28S (1988 US model), DM41X (2020)
