I'm looking for a new scanner. If you have one, please post comments here. So far, these are a few that I like.
Yaesu VR-500, $300
Yaesu VR-120, $175
ICOM IC-R2, $160
The thing that gets me about the cheaper ones is how easy it is (or isn't) to change the frequencies so that I can monitor a particular aircraft as it moves.
