The fx250/260 series are the best non-programmable "trig" calculators ever
manufactured (in my opinion!). They do just what we need them to, they do it
right, and they are now dirt cheap. I've got three of them within twenty feet of
me right now because they're such a great value.
You mentioned the sexagesimal (deg, min, sec) input function earlier. I was
amazed to discover when I bought an fx-260 solar-powered model last fall that
this function has been refined even more. Whereas earlier versions displayed the
angle always as decimal degrees, this newer model shows deg, min, sec separately
which makes typos much more obvious. It also does inverse conversions when you
want to get deg,min,sec from decimal degrees. These are trivial matters in any
expensive computing device, but it's just amazing to see it in a calculator
that costs less than eight dollars.
