For the very limited range you will get out of them you better of with FRS or MURS. CB handhelds tend to be physically large, are battery hogs, tend to have very poor antenna and range is very limited with the built in antenna. Unless you need to interact with mobile/base CB's your better off with anther option.
If your need a CB then the MIDLAND 75-822. is a nice combo, portable with a mobile power supply.
