The BCT15X is an excellent scanner, BUT a real pain to program and learn. I've had mine for about a month and have spent over 100 hours messing with it, so there is a very steep learning curve. You won't have a paper manual, so you'll have to be close to a computer if you need to refer to the gazillion key functions or if you get some thing messed up. You will mess up ALL the time trying to learn, so be warned.
FreeScan for your computer is free and almost mandatory. I wanted to know how to program by hand and know my way around the scanner, so I tried to stay off FreeScan. Depending on your frustration level that may not be possible!......
Out of the box the 15X has the basic Police, Highway Patrol, Dept. Trans. pre programmed, so you should get a decent amount of traffic if you travel. I saw some where that the amount of digital around the country is less than 15%, so other than large cities I felt it wasn't worth spending $300 more for digital. You'll miss out on some, but if you are traveling you'll have a huge amount of frequencies available for years to come.
