Yes, backordered sockets is not good for us, makes up all of our PFO kits. Hopefully wont' be too long. ORdering the sockets elsewhere is no problem, just make sure they have the new 3 prong quick connects on them and PFO brand, otherwise they won't match up.
We have some LN sockets, but it would be worth getting PFO so you don't have to do any wiring.
