I'm sure that quality makes a huge difference. However, I bought an el cheapo from Harbor or one of those places and have had no problems with it at all. My Grandfather showed me how to use the tap and dies years ago and he always stressed going SLOW and backing up often to clean the burrs when tapping threads. I guess your amount of usage should probably determine your purchase. Good Luck and let us know what you decide and how it works for you.
