so what's the difference in all the injectors?
so what's the difference in all the injectors? been lookin around for 42lb injectors...wow there are alot out there and why are there so many kinds and why all the big price differences? is there that big of a difference to pay $100 more for the same injector size? are they all pretty much the same...just different names?
just found out that the Lucas/Delphi can be up to 7% off from one injector to another in the same set. wow...
what I'm looking for are 42lb injectors that are VERY close to the same flow rate since I will be spraying a pretty decent size dry shot soon.

Variations of that magnitude are EXACTLY why one should purchase injs in flow matched sets ONLY...[The "family sedan" can tolerate the mismatch, the hotrod cannot.]
Case in point: Just flow matched a set of 160's, for a 10.5 SBC.. I went thru 24 injs to get 8 that were close enuf to use..
I went through Deatschwerks on Ebay to get my Bosch 30 lb/hr flow matched injectors. The price was good, but mine were previously used injectors. Didn't matter to me though...they are being used even more by me 
I think that is why their prices are a little lower than most...so far so good though. Comes with a flow sheet, and all of the injectors are numbered so you know which ones flowed what.

Looks like they use core injectors, so that would explain why they look used (they are).
As for the difference among all 8 injectors in my particular set:
Static:
100% duty cycle (43.5 psi) - 0.3%
Highest flow was 314 cc/min, lowest was 312 cc/min.
Dynamic:
75% duty cycle (43.5 psi) - 1.4%
Highest flow was 249 cc/min, lowest was 242 cc/min
Since they were numbered, I put the highest flowing ones in the back of the intake manifold, and went forward from there so the lowest flowing injectors were at the front.
