Are you a HAM? Many amateur transceivers offer VHF airband RX. I currently have an Alinco DR-135T both in my mobile and base setups.
Also, check out the used market for the Icom IC-A110, it's a VHF airband transceiver that normally has a VFO as well as 20 memory presets with alpha tags. It supports scanning, though it scans very slowly. Only trouble with the IC-A110 is it is affected more by interference than most Icom gear and I would suggest a bandpass filter for it. Works fine without a microphone connected if you're worried about accidentally keting up. Works on both 12V and 24V nominal systems.
Edit: Some of these Icom radios might have been programmed to not allow scanning, front panel programming or an open VFO.
