They're not junk, but they have limited usefulness due to the permanently mounted antenna, and the constraints of the frequencies. As Johny suggested, a better option would be a radio with frequency agility. The Chevy or Ford of radios is the Baofeng, with the UV-5R the most common due to its inexpensive price. Baofeng does manufacture some better models, like the UV-9R Pro, which is waterproof, or the AR-152, which is very robust and has a extremely large battery. Both models can be found in the $45-60 range. Both radios cover FRS/GMRS bands, MURS, NOAA weather channels, and of course, some amateur radio bands.
