Injector nozzles UK

[Basher]

Ordered a set of nozzles from eBay that came from Germany, went for the cheapest as of the ones advertised they don’t state a manufacturer.
Anyway pulled one of my injectors today, it had a poor spray pattern so I swapped the nozzle, all was good but it was not holding pressure and leaking around 1800psi, the second one I tried would open but not close again and the 3rd one I took out was completely wrong and had a point on the rear of the nozzle instead of the small rod.
I stuck the old nozzle in my ultrasonic cleaner and then rebuilt the injector which solved the spray pattern.
Now I’ve been refunded from the seller but I can’t find nozzles unless it’s unnamed or bosch at £60 a nozzle, anyone know of a supplier where I can get quality nozzles, or I may just strip and clean mine and hope none are dead
