Alternatives for FEP Film for Photon Mono 4k???

This is more of a cry for help. My FEP is old and scratched over 2 months of use. I placed an order on a new one from the anycubic website. 2 weeks passed without any updates and I emailed them, just to wait for an additional week for a reply, that they are out of stock and the wait time now is 1-2 months...
Could you advise a 3rd party alternative, because I really don't want to wait 2 months for a FEP.
