If you are getting into the hobby, Amazon has a wide selection of Chinese radios. You have to start somewhere, and the barrier to entry is low.
Baofeng UV-5R - the ubiquitous Baofeng
Baofeng UV-S9+ - my Baofeng of choice for the USB charging
Anytone AT-779UV - my mobile radio in a box
DX Engineering is my go-to online retailer for Amateur radios. They are a part of Summit Racing and are rumored to ship from the same warehouses. Great selection of equipment all around. If I'm going to spend money on the hobby, this is the first site I go to.
GigaParts has a solid selection of radio but also a wide selection of “other” stuff that makes it unique. Custom items, computer parts, and gadgets are some of the many things GigaParts offers.
Ham Radio Outlet has multiple locations around the US, and you can go into the store if you want to put your hands on some equipment. I have ordered several radios from them, and I've always had a good experience.
