APS is the way to go as far as aftermarket cabling goes (just an opinion...). Recabling them is easy...the armature element (the "barrel") is connected to the cabling by two pins. If you have the older red/blue ER-4's, the colored parts are where the pins are. Anyway, order the length you want, any options, and Alex will get one built for you. For one thing, you'll have a continuous cable from plug to pin, not a spliced up mess that is the stock Ety cable.
