I have been using the Baofeng uv-82 for several years . Any of the programmable Chinese radios will be a little harder or different to operate than the strictly GMRS radios . But they also have more capabilities that could come in handy . Mine are programmed for Ham , Fire Department , GMRS , FRS and I can easily program the maritime frequencies when I want to monitor boating traffic such as river boats .
The Baofeng's are easy to use and program with a little practice .
On 19 acres you shouldn't have any problem with coverage . We use ours on 40 acres with no problem . I have four handhelds and loan them out while jeeping . I use a mobile in the Jeep and have talked to my portables over a mile away with clear communications . I've used the uv-82 to get into repeaters well over 20 miles away , sometimes further depending on the terrain .
The uv-82 is inexpensive and durable . I chose it because it is a little bigger and fits my hand better , more like some of the Motorola radios I've used on the job . I've used my uv-82 at work and it seemed to be just as clear as the Motorola , just several hundred dollars cheaper .
They do have a new larger 10 watt uv-25 portable radio which has even more power and features . I'm not sure I would want a 10 watt portable next to my head transmitting . 5 watts is relatively safe exposure , when you start adding power , you need a remote mounted antenna to get the rf away from your head .
