Jeremiah,
Welcome to the Creek. Your profile doesn't indicate your location. You may live close to another member who would be happy to let you test drive their chisels before you make a decision.
I have never tried the Narex chisels, but from the comments of everyone here who has purchased a set they sound like a good buy.
If it is possible for you to attend a Tool Event (sponsored by Lie-Nielsen or another wood show) you will get to put your hands on some of the different chisels to see how they feel in your hand.
To me the feel in my hand is important enough that almost all of my chisels are socket chisels so a quick session at the lathe can make a new handle to my liking.
