Rich, I guess choices is like bellybuttons... everybody's got one
I chose Dorman because I've used it before, and it's not cost prohibitive for us retired folk, such as AN fittings and steel braided lines. I'm not adverse to using steel tubing, 'cause that's how I make my trans cooling lines. I just find the nylon tubing to be a little dressier than rubber tubing and clamps.
Eric, that's what I did, just purchased the tool and whatever supplies I needed, all available at my local real automotive parts store (no kids, no computers, real parts guys)
