If I'm looking for a cord, how does the Marinco EEL (+ Smartplug connector) compare in quality to the premade Smartplug cord? Smartplug's claim to fame is electrical safety, so I assume that they make a good cord and as good a dock-side connector as possible (given the old twist-lock form factor on that end). But the Marinco is more likely to come on sale, so if their cordset is solid as well, I might watch for that one and replace the boat end with the Smartplug connector (the overall price difference isn't huge, but I'll save a little if I can).
