I think there are plenty of GMRS repeaters out there to get the job done. There is a Wednesday night net where you have people talking to each other from coast to coast using the GMRS repeaters. I have my radios on in the background sometimes and there is easily 10 times as much activity on the GMRS freqs. Plus the license fee for GMRS finally dropped to $35 and no test.
The Baofangs are pretty nice just about all in one units. You can receiver and transmit on 2m, 70 cm, MURS, GMRS frequencies, let the sad hams squawk about how that's not allowed.
They are super easy to program using CHIRP so you can program them for repeater tones and offsets as well as wattage output.
I'd get a Baofang UV-50x2 and an appropriate Nagoya antenna on your roof and call it a day for an in rig unit. You can program it to transmit up to 50 watts, plus different wattage on the same freqs on different channels. This is what I'm using in my trucks directly wired to the battery. You can also get a UV82HP hand held and use an external antenna with good results.
At my house I have Yaesu, Baofang, and TYT transceivers on every freq from GMRS, 70cm, 2m, 6m, 10m and CB. Once I get more than my Tech I may move further into the HF area.
