J.E. or coast are pretty well spoke of all by everyone. If you are wanting personal experience then look no further than to tons of people speaking highly of these companies. Their track record is proven, but for that same reason they get to charge more and make more profit off everyone. Nothing wrong with that as it shows they have a quality product.
There's a company called Adam's and they make custom shafts. If you go with a 1310 you can get front and rear for around 650 shipped to your door. They only use those same made in the USA Napco joints as well. So thats a big plus in my opinion and for that price they are a heck of a deal.
I know the price goes up significantly if you do their 1350, and become more of the price point that all the other brands are selling for. At that point the value would be up to the consumer. I like supporting the little man if and whenever possible within a budget.
I have never personally used that company or shaft so cant speak from experience, just by word of mouth just like you're getting now from me and all others. But for some of those small reasons, I still may go with them on my purchase if I decide to go 1350 :twocents:
