Ritron has some basic base stations. They don't look like traditional radios, more like an intercom. Bonus is they have their own power supply, so no rigging up your own.
The FCC certifications required for MURS sort of limits most other radios, if you want to stay legal. There was an old Motorola Radius mobiles that were 2 watts only and would technically be grandfathered in on -some- of the MURS channels due to the narrow band/wide band requirements on the channels.
Issue is, those radios are really old, and not many of them out there. Those that were got snatched up by people who knew what they were.
Other option was an old Radio Shack 'vhf business' radio. It met the requirements, but again, people snapped those up quickly Probably still a few out there if you know where to look. I —think— it was this one, but it's been a long time, don't rely on my crappy memory:
