How is conversing with me pointless? I disagree with your statements using fact and knowledge and your rebuttles are simply "I have done them, they are fine". That's like a smoker saying I didn't get cancer. It hasn't happened yet, but the odds are good that it will someday.
Making statements about how good things "can be" is going to lead a lot of new members who read threads like this into the wrong direction.
And there it is. Nickel and Diming because you don't want to spend another $75-120 on a quality used cam, or a little more than that on a brand new cam from a company like comp with 36 years of track proven experiance.
To me that $75-120 is insurance, but hey... Some people like to take risks.
