When your fave mask is discontinued

ETA & TLDR: I’m looking for something that either is or is similar to the Drager X-Plore 1730 (ffp3). Main characteristics: bifold, headstrap, additional external nose wire, good for big faces, available in UK.

I’m wondering if there’s anywhere that tends to have stock when other places doesn’t (I’m in the UK though & don’t want to deal with customs charges/postal delays so would need to be here), can eBay be trusted at all…? Or is there any resource that’s like “if you loved that mask, try this…”? Or do you know of a bifold with headstrap that also has an external nose wire (and yes, I have tried adding my own to an existing mask, it did not work)…?
