I'll help you out brotha, I bought these a long while back on amazon they still sell them they are 60cc syringes and 14 ga x 1-1/2". The needles are not pointed but are open and make a smaller hole then other injectors, they are not the vet kind but they work well. They also screw into most cheaper syringes like the red one in the picture. I used them for brisket/butts when I thought you had to inject to get things moist, what are you wanting to stick?
The Spit Jack I think is the best . I just got on for christmas with 3 needles and case for $60.00 . It is the best injector I have. I have had many injectors and they all have not lasted. This one is built to last . Just have to watch for sales and special codes to get a great deal .
