there is a guy on ebay (located in Austria), offering a lot of OOP items, such as Isradecal Nesher decals.
Beside the prices he is asking for, there is a lot of interesting things he is offering also.
I´m a little cautious as there are multiple sets "available".
Maybe not WORTH buying, but worth having a look on.
I bought a few months ago a decal sheet from Antarki which has a lot of decal options including an IAF Nesher.
