I got this chart as a reference guide to aid me in my (very intensive) Latin course at university. The chart covers everything that I'd certainly need to know and would be very suitable for anyone studying Latin from beginner right through to university level.
The one downside to the chart is that, as it is published by an American company, the order of cases for nouns is that used in the USA and Europe - and not that used in the UK. By this I mean that the case order most UK students will be used to; nom, voc, acc, gen, dat, abl is not presented in favour of the US and European system of; nom, voc, gen, dat, acc, abl.
This makes little difference ultimately, but can be a bit frustrating when getting used to using the chart for the first time.
