Nasty talk isn't too bad around here or on the interstate - most people on I-40 between Memphis and Nashville are pretty helpful and usually just stick to business.
I don't want to start ranting here, but you're not going to be happy with any radio if you cut corners with your antenna. I've got over $350 in just my radio not to mention the mic, coax, antenna, and external speaker. I put up a cheap magnet mount antenna before I had a bracket made for a permanent antenna and it nearly made me hate my radio. It had no range whatsoever and wasn't much help over 5 miles.
Here's my "close to expert" advice - don't buy a radio from a truck stop or a CB shop. Truck stops have a markup and CB shops are ungodly. I've seen CB shops charge twice the price that you can get radios for on the net.
My #1 recommendation for a place to buy a radio and coax is
1 Stop Electronics. You can get all types of radios there and they will also do the "tweak and peak" for you so it will sound its best. For an unbelievable online shopping site,
Walcott CB has the best place I've ever seen. They have EVERYTHING but their prices on the export/amateur radios are just a tad higher. I recommend them for all your accessories and antenna.
You can get the best deals on mics on eBay. Truckers will tell you that the best mic is a Turner/Telex RK56 but the best mic I've ever used is an Astatic RD-104 Road Devil power mic.
As far as brand of radio - most truckers will prefer a Connex or one of the "General" models. (a General Lee is the same as a Connex 3300HP) I believe that a Connex is the best radio out there - especially for the price. You can get a Connex 3300, which is a staple in the CB world for less than $180 at 1 Stop. This radio has side bands with echo and talkback and is extremely powerful. Talkback is really fun if you talk on one a lot, but you really need an external speaker ($20).
If you don't want to go with a Connex, I'll put in a plug for a Cobra 29. This was my first radio and I took it to the 163 (exit) off of I-40 and got them to "super boost" it and put a Connex board in it. Lots of people said it was the best sounding 29 that they had ever heard. HOWEVER, after I sunk all that money into it, I had just as much money in it as I could have bought a good Connex for. Wish I knew then what I know now. I've also heard good things about a Uniden. Walcott CB has a Uniden PC78 Elite with a $40 rebate right now. It's probably the coolest looking radio that I've ever seen. The face is backlit with orange lighting.
As far as an antenna, it's really hard to beat a good ole Firestik. But most truckers will prefer a Wilson 2000 or 5000.
Didn't mean to write a book - I tend to get carried away on the CB talk. Shoot me a PM if you want any more info. I'll be glad to help.
