I have the Cajun Injector (green) one and it has held up well through about a dozen uses so far. Got it on sale at Gander Mountain for about $10. I bought a jar of CI creole butter for the Thanksgiving turkey and it came with their basic model so just for the heck of it, I used it on two turkeys and it worked okay as well. Funny thing is, my CI "deluxe" model came with an extra needle that fits the basic but not the deluxe.
