I haven't seen/heard any modern solid state amateur rigs do AM equivalent to a CB, the dynamic range is just not there because of the tight front ends and filtering, even with the optional AM filters installed. Reception of AM on modern ham rigs sounds flat and bassy as does the transmit. On SSB, the dynamic range of the audio is usually comparible, but the ham rigs perform better, with better rejection, and cleaner audio, so you could use it on 11 meters SSB.
Most CB's have really wide front ends and filters which makes for more pleasing reception of all those trashy overdriven signals that are all over the 11 meter band, but at the price of getting more adjacent interference too. The CB's also tend to have better noise blankers and reduction units that just work better on AM.
If you are into AM CB, you probably will not be happy with a modern ham rig for that mode but it will work on SSB. Nevertheless, if you have your heart set on a ham rig for 11 meters AM, probably the most popular is the Yaesu FT 101E or 101EE. There are tons of these radio out there, the only problem is they use sweep tubes, that are getting harder and harder to find and more expensive, like $70 each, which will not last long using them on AM. For SSB, most of the vintage rigs from the 80's probably will work ok.
