I wouldn't hesitate to recommend the API master kit to a beginner but after that I found it a waste - of money, of plastic and of chemicals. Straight away you don't need one of the pH testers, then one ammonia reagent runs out way before the other so you throw that away, then you run out of one of the nitrate reagents because that's the one you use more than the other tests.
I've tried a few nitrate tests and prefer the Salifert because it only has two steps, it doesn't need shaking and the levels are not too broad (0, 25, 50...). I'd prefer the increments to be smaller for accuracy though.
Many people object to strip tests but I think they're fine - I find the API strips match the readings of liquid tests and the increments are on a par with most other tests. Again, beginners would need to be aware of the need to test ammonia but this is rarely needed after establishing a tank.
