I got mine from Kopterdreams and it was delivered in three days. It's a well made adapter but make sure to plug it into the charger before attaching the battery to avoid shortingLike you say Third party chargers best solution, I don't know what supply of the dedicated charging cable are like, a few have posted links, I find websites claim to have items in stock, but quite often it's for order, I think you'll have to do a bit of detective work and see who has them.
