This neat little radio can be had for around $30, and I just picked up a couple to use on GMRS. If you are interested in one for GMRS, the new ones have recently been changed so that they will not go to the GMRS frequencies. There are still plenty of old ones out there, so check the specifications to make sure you know which ones you are getting. I programmed mine for GMRS and marine frequencies for when we go to the beach.
This guy has a ton of GMRS videos.
