Ok. Here is my take for what it is worth. I think everyone on here will overpay for something that is guaranteed to solve a known problem. It gets finicky when a fix for a problem some have and some do not is perceived as expensive. Comes down to individual idea of expensive or cheap. If you are blowing $200 belts ( Or Whatever the cost ) $150 is cheap. If you have rode 2000 miles and never blown one it is a waste of money. A $5000 turbo gives you a definite and noticeable improvement in performance whereas a $150 adjuster may not seem to do anything and therefore is a waste of money ( trust me been there ). Bottom line is buy the products you think will solve the issues you have and skip the ones you think you do not need. I see both sides of this thread as I have owned my own business for 17 years. If you have to charge a perceived high price ( yet fair ) for a product that may not be necessary it may cause some negative feedback. At the same time to all those who have not risked everything to start your own business, well you will never understand that we work twice as many hours as you do for sometimes half the pay. Unfortunately this is a very expensive sport and if you piss like a pup, stay on the porch. Sorry that is just the way it is.
