What liquid test kit works best for aquariums?

I've recently set up a 29 gallon aquarium and am currently doing a fishless cycle in it. I am using API Ammonia test strips for now until I can get some Nitrites to build up. I've read multiple fish fourms on how test strips constantly give inaccurate readings so my question is, what liquid test kit works the best? I know that API makes a liquid test kit but I'm a little leery to buy anything from them now since who's to say that isn't accurate either. Also how much are these liquid test kits and where can I find them?
