Tubex Injector vs. Carpuject

Does anyone else feel this way about the Tubex Injector vs. Carpuject?  

Need some help: I am looking for a Wyeth-Ayerst Tubex Injector.  I know they are out of production, but cannot stand using the Carpuject)….if anyone has one of these TUBEX, I will buy it from you! Or, do you know where I can get one?THANKS!!!!!
