Casio - king of calculators,
This review is from: Casio FX 83 ES Calculator (Office Product)
£4.98 in Staples in August 2009. At that price, no contest.
I still have Casio's that are 30 years old - still going strong. They've not changed much in that time - because they had it right first time around - the key action is perfect and totally reliable.
The natural display is a real step forward though.
Why have I bought new ones? The kids need their own now - mine are still going strong and have stood the test of dropping and general use and abuse over a long time.
Down sides? The slide on cover is a little fiddly. I don't think these ones will last 30 years, they don't seem quite so robust.
