I have the matco kit and while it works great, the gauge glass (plastic) became difficult to see through. I clean it and put it back in the case after every use too. I had the stant tester that I bought from Carquest and it was great, unfortunately I gave it to a friend since I had 2 testers. I think I gave the wrong one away though.
I found the cooling pressure tester great for finding leaks. Pressurize the system and you can readily spot the leaks in radiators, hoses, etc, without the noise of the engine or moving parts in the way.
