Getting through the fake of it

I'm in need of replacing the Injectors on my 8.3L ISC Cummins. I went to Cummins directly, and was quoted $189 + core ($200) each. Well, unfortunately I don't have $2400 to shell out today to pay for these things, so I went searching online. Now, I must be brain dead when it comes to searching online, because I'm having a hell of a time finding real injectors. I have a Cummins part number for my engine, but even so, I cannot find a cross reference number to a Bosch. Ebay and Amazon will bring up "genuine Cummins injectors", and for some reason they'll post a Bosch part number with it (fake?). If I was going to put non OEM injectors in my engine, I'd rather a name be associated with it, not a clone. Does anyone have any suggestions on places to look? Maybe its time to dump Google as my search engine.

 

Yup, alternators and starters are what I don't need. 2000 Freightliner FL70 isn't in the passenger car list, and the Cummins number (3944208 ) doesn't cross reference. Been there, tried that, still not getting anywhere. I was pretty sure I had tried the obvious, but maybe I missed something.
