After reading the FB post, I went online to Amazon and bought a spare for $31. I'll leave that one in the box until I actually need to use it. The plain old Holga 120N -- my favorite. You may love this article I found from 2012.
So, stock up while you can. In 2002, I paid $15 for a Holga, and now they are over $30 each. You can also buy a true bargain, the Debonair Camera from the FPP store for the very reasonable price of $19.99.
UPDATE: It's official. Phone call to Freestyle confirms closing of Holga.
