Velcro is awesome.
And to answer your question.. YES! Cbs are great. Theres nothing like going down the highway and asking for a bear report (police report). and PAs are a MUST! I love mine.
Heres my recommendation of what to buy:
Midland 1001z 40 channel CB radio
I recommend an extension speaker with it.. they make audio much clearer... - $20
Lil Wilson magnetic mount (should you choose to go this way) - 35
PA speaker: 10-20 bucks..
Seriously its about hundred or so bucks. Well worth it!
Hope that helps.
