Looking for graphical calculators up to £60 that are both completely legal/allowed in Edexcel 2009 spec Maths and Further Maths AS and A2, and that would be useful enough for both to justify the cost (my current scientific bog-standard Casio is good enough for now, but if things get tougher I would likely appreciate the help of a graphical calculator). The Casio FX-9750GII looks good, but if there are better ones for slightly more or comparable ones for a bit less, I would like to know about them. I would consider a Texas Instruments one if I knew which one was exam-legal (TI84? TI84 Plus?)
Suitability for OCR Physics A 2015 spec not necessary but would be nice.
Then says she misses me!
