I have the 396T, I love this radio, but the 106 would be a better radio for you. I got the Uniden 396T for one reason, it will scan in the 70 MHz range where GRE made scanners will not. The TN Highway Patrol has one weird setup when it comes to communications and without access to the 70 MHz area, you get one sided communications if you live in East Tennessee.
The 106 will receive much better than the 396T, but is more prone to front-end overload while receiving strong signals close to you. You can turn on the attenuator to fix this problem though, the 396T is a little weaker on receive and doesn't have this problem.
So to end this, if I were to buy a new scanner right now, the 106 would probably be the one I would choose.
Have fun and enjoy your scanner
