hello there.
you can wait for maybe next khloes mo or you can visit perlyinc.com to purchase your holga. well the holga uses 120mm but sometimes jimmy conducts mo for the 35mm adaptor designed for the holga. here is the link for jimmy's mo but i think it's closed.

or you can check out www.8storeytree.com and if you're lucky there might be stocks. and if you buy the holga, you can just get the fisheye adaptor.
