I like them too, as well as the NAPA Premiums. Good belts are one of those things that are truly worth the price; it's a part that needs to run for a long time with no possible issues. Cheap ones have problems with amazing regularity....
I avoid the Gates ones with the notches on the outer surface, because I had 2 of that type from Dayco (their Top Cog type) and they were plain and simply crap .... they slipped like crazy if they got a bit loose, glazed up, and then would slip all the time without any noise.
