In an update on the Haslab, it's still sitting in the 4,000's.
Meanwhile, the Ghostbusters Proton pack, which costs almost twice as much and has a more niche adult collector fanbase that wouldn't in the past fund the creation of an Ecto-1 that fit 6-inch action figures thru Mattel Creations, is now almost funded, closing in on 7,000 backers.
