Honestly, I'd used a used junkyard/Ebay one over a lot of the electronics being sold today, even some motorcraft electronics. I'd search and buy some OLD NOS ford or motorcraft parts.
10-20 years ago, there were still plenty of 5.0 powered Fords, mercury's and lincolns on the road, so there was more incentive for manufacturers to compete for that market. Now, it's just the fox enthusiast market, which is relatively small in the grand scheme of things. The market for these parts is dwindling and we are down to the lowest bidder in a pool or 2-3 manufacturers. Quality is down.
