I'm a newbie with a BCT-8, first scanner. I like it so far, but have little else to compare it to. I have one gripe, and that is that you can't duplicate frequencies among banks. One of the first things I tried to do was to set up two duplicate banks of the same trunk system, so I could have more scan list id's. No can do. But once you find the interesting channels you'll find you can weed out bunches, and hopefully come up with lists that have some semblence of order.
I also wanted to point out, that what the others said about the digital trunkers is true - but be warned. It's a HUGE step up in price.
