Well I finally got a complete set of injectors and tested them, which didn't quite go the way I thought it would.
A few of them took almost 400psi to "pop" the first time, and several also did not have a fine mist spray pattern, but more of a forked spray.... It took a few really good flushes with the tester to get them chirping and spraying the way they should. They are all perfect now, holding pressure the way they should instead of dribbling etc.
Of course I mounted them in the test stand and hooked the 6 lines up and plugged the power supply in, and "ZAP!!" there was quite a spark as I plugged in the ebay special 12V regulated power supply...... and nothing. I guess that $12.99 bet didn't pay off but you can't win them all.
New power supply should be here in a week or so.
