The biggest problem with handheld CBs is they require too much energy, which means a lot of batteries. They are usually rated at 4 watts output, the same as the ones mounted in cars, but with the antenna mounted on the radio they will not give the coverage of a car mounted radio. But the antennas are detachable which will enable you to get better reception depending on conditions. Cherokee used to make, I don't know if they still do or not, a sideband handheld that had an output of 12 watts, but then again, the more power it puts out, the more power it takes in. I would still take a HH CB over a bubble pack FRS/GMRS radio any day.
New FRS/GMRS radios are not worth the money I paid for any of mine. The early FRS radios were well built compared to most of the toys put out today. The combination FRS/GMRS radios are mostly ad hype and no matter if they are camo or not, they just aren't that good, especially comparing them to a "real" GMRS radio. FRS radios must have an antenna that is not detachable, which means any FRS/GMRS radio is going to be compliant. Also, no matter how many channels the package tells you the radio has, it really only has 22. Real GMRS handhelds would be the best way to go, 5 watts of output and a detachable antenna, but they require a license, just like operating a FRS/GMRS radio on the GMRS channels/frequencies.
There is another option too. MURS radios. They are allowed up to 2 watts of output power and can have detachable antennas. They have been legal for a long time but have not gained the popularity of the FRS/GMRS radios, probably because there are only five channels in the MURS class, but did find favor for use with security devices. (google "MURS compatible radios" and you should be able to find some.)
Of course cell phones would be the best if you are in an area that is covered. There are other radios that are better than the CBs, MURS and GMRS/FRS, but they require an FCC license and I'm not going to discuss them on an open forum. But the best suggestion is to look into getting a ham license. Pass a 35 question test and you're in the door, then if you feel you want to go further you can, after that the possibilites are endless.
