It depends, do you want to be legal or not? Legal is 4 watts am, 12 ssb. MOST of the Galaxy and Connex rigs are listed as 10 meter ham radios that convert easily to 11 meters. CB's in Ham's clothes if you will, with way more than legal power!.
I don't care mind you, I'm legal now, but moons ago I was far from it, but I can't condone or encourage that type of behavior, I can simply just state the laws now.
I was a big fan of the Cobra 148GTL, which actually just got re-released, it's about all the features you could want in a rig and probably more!
The Wilson and K40 antenna's are really at the top, spend the money, or if you have the room/vehicle to accept it, get a 102" stainless whip and some GOOD coax and connectors.
Really, a hand held CB is a joke, all it will do is make you angry! Sure you can hear on it, but unless you are within a 1/4 mile, they wont hear you!
