Can't go with the HP's as it is for academic purposes (tests), and the 991EX is one of the better calculators allowed for tests and exams. But thanks for the links I see HP has some nice calculators I might have use for. The HP Prime also caught my eye.
I bought it off eBay, shipping from India, anyone perhaps know how long it normally takes from there ?
I recently ordered some items from China and I know that can take a while, took about 3 and a half months before I received it. Is it the same for items shipped from India ?
