CBWorld

They have the widest range of scanners out there that I have found online. Got me a police and radar detector for pretty cheap. I know these days those detectors do not always work but so far mine (15 band) has saved my ride a few times now. For safest bet buy 2 detectors both different brands, make one cobra and you are most likely going to be safer.

These guys have a ton of CB stuff. Definitely more than I've seen on any other site. There prices seem to be in line with others, even the bigger sites. I wasn't able to get right through on the phone, but they guy called me back pretty quick. Good people to deal with.
