Hi
cfournival,welcome to RadioReference
That $150 budget will limit you to only a few basic models.
If you
do not need trunking, perhaps a Uniden BC350C would suffice.
Used, older models with more features may be found in the Classified forums if you are lucky for $150.
What area do you live in and what do you want to listen to?
This will put a better focus on which scanner would be suitable .
Perhaps you can save for a while longer and not be disappointed with your purchase.
