I think I am going to be purchasing an OnGuard Bulldog Mini but I have some questions. I am confused by all the different locks. For instance what is the difference between the Bulldog Mini and the Bulldog STD, ATB, and LS? Also if the Bulldog Mini is "mini" why is it offered it 2 sizes? One of them being just as long as the Bulldog STD and ATB. I just want to be sure I am getting the same lock that was tested above in '05. Any clarification would be appreciated. thanks.
