I, for one, have really had enough of all the chips on the shoulders here lately.
I didn't call anyone out for their choice of valves. I didn't say Alex's valves were junk.
I just made a blanket statement, saying that you have to watch what you buy on Ebay. There's been an emergence of a whole lot of parts in the past few years, and just because it's cheap, a good deal, and the seller says, "Hey, these are quality stainless steel valves..." doesn't mean squat. Buyer beware.
If you've had excellent service and excellent results from Alex and the EPN stuff, then that's great. However, not all sellers on Ebay are like Alex.
I have tried them all...Ferrea, Manley, EPN, REV, you name it. There are different grades of stainless, there are different finishes on the valves, there are different shapes, and they all have their purpose.
