I have a Uniden BC9000XLT. It is 500 channel conventional only scanner. Have had it for several years and would not part with it. Excellent reception in all bands. Alphanumeric tags for channels 1-250.
Look at the Radio Shack PRO-433. It has all the regular bands plus the Military Air band 225-400MHz. Very rugged steel case and chassis, good audio, comes with DIN car mounting adapter and A/C adapter. Only $169.99.
Conventional public safety type stuff? VHF? 800MHz? Are you interested in milcom listening? marine band? Rail? Knowing what you want to use it for would help in making a reccomendation.
