I missed out on the E4 plus deal on amazon but found this on Jet. It doesn't specify E4 but based on the specs it seems to be. Worst case scenario you can ship back for free. If you need multiples, it's under $100 each.
Hope this helps someone. It's my first post, please don't crucify me if I did anything wrong, if this is a bad deal or a repost, I searched before posting.
