I guess the easiest answer is, it depends.
If you are in the US - and I am guessing you are, based on the fact that the FCC only regulates the frequency spectrum in the US - then what do you want your radios to do? If you want your own frequency assignment and be able to talk to other users of your own radios without interference, then you would apply for a business licence. It can cost several hundred or more, and you pay yearly for the privilege of your own assigned frequencies. You will also need Part 90 radios.
Your radio dealer can handle this for you.
If you simply want to talk to your other radios, family, friends and others who may be on the same frequency, then GMRS is the choice. You share the same 22 frequencies as everyone else but if you are lucky enough not to have a bunch of kids, local drive-throughs or businesses within range using up many of those frequencies, the FCC GMRS licence is much cheaper. It also covers other family members.
If you want completely licence-free, there are some good FRS radios on the market, and you can transmit up to 2 watts. (Many handheld radios only transmit about 4 to 5 watts on the UHF spectrum anyway, so 2 watts is not much of a deterrent.)
As far as getting your ham licence, that opens the world. You don’t need an FCC licence for ham (amateur) bands because these are the spectrums that are open to amateur “hobbyists” instead of businesses.
If by talking only to your own radios means you are chatting or using them emergency communications, the amateur bands might be the way to go. If you are going to conduct any business over the radios, then ham is NOT the way to go.
Hopefully this helps.
So we can’t really answer the question for you unless we know what you want the radios for. As far as radios, you need to decided what type of licence if any that you want, THEN decide on the radio. There are literally thousands of brands of radios out there and most are garbage, with high failure rates out of the box. (Read these forums and you will see what we mean.) For a bit more money, you can get a quality radio, from a quality dealer, and with quality accessories. Trust me; you will thank us later.
