I've bought a couple sets now from him as well as the stuff to make my own. He sold me custom ends, etc. with auxilary attachment points on them and I soldered them all up, put two extra 10 ga wires in it to run my relay ramp (horn, headlights, tail-lights, etc.) and the parts were top notch. The guy takes a little time to get them, but he uses VERY fine braid wire and everything is soldered and shrink wrapped with adhesive shrink wrap, etc. I won't use any crimped on again since learning how to solder them. I made up extra 4 ga ground cables, etc. and everything seems to work so much better, stable in dash gauges, etc.
You won't be sorry, like I said, it takes a minute to get them, but several of us have bought them and I've not heard any complaints other than the time to get them. I've talked to the guy several times for parts since then, I can't remember his name, but he's a very nice individual and when I order parts, he always throws in shrink wrap and such...generally he just says, "oh, I'll set you up for $20" or whatever the price may be, and when he says set up, there is nothing lacking. Great guy! Should be on our "merit" list if he isn't already.
