The last one I bought was a Beck Arnley and seemed to be a much better built unit than most I've seen.  I had a fail-safe Stant fail right out of the box, and had a regular Stant lock up and cost me an engine.  As far as Napa parts go, I steer clear of them if possible.  We use a lot of their parts at work and they're junk, and frequently fail right out of the box.  I don't shop at Kragen or Jesse James Zone unless Franklin is closed.  If you know your brands well enough it doesn't matter where you shop, just that you know what you're getting,  Nate
