I agree...
This is one of the main motivations behind this website. I wanted a place that the average person could go to and see for themselves what the benefit would be of certain devices, or how to build their own for very cheap. I am considering selling kits for many of these devices (PCV catch can, vacuum switch to kill AC when accelerating, etc.) for a very small market. hell, if I charge $40 for a PCV catch can made from Home Depot parts I'm pretty convinced that I could sell a few a day.
back to the point.
With these devices, there is a certain ambiguity invovled that most people fall for. It's a car, it's a big mean machine, and it scares people. Even some of the racers I chat with on other websites (who you'd assume know just about everything there is to know about cars) get scared when it comes to their engines. A lot of them are afraid to do an engine swap, or change a clutch. I figure if guys who have cars as a hobby are afraid to do some of this stuff, how much more afraid will everyday people be of this stuff?
The sellers of these products are just doing what every other business has done in the past. They are taking advantage of people and letting greed rule them.
So basically, I understand your frustration
