Amazon.com : Texas Instruments TI-84 Plus Graphics Calculator, Black : Office Products

My daughter uses this for school. It was the model that she was advised to buy. I rang up customer services at the company selling this before I bought it to clarify a point and they were very helpful and polite. I think I rang up to see if it was available in purple and was informed yes- but only in the USA. Here, in the UK, the only color available is black. Delivery I think was very quick. My daughter has been using it for a few months now and is very happy with it.
It is expensive for a calculator so obviously it is one of those items that you have to buy.
