You don't need to worry about folks with ordinary scanners listening in with digital and DSS models.
Though you can't find a good 900 MHz digital or DSS phone retail anymore (since they can get more money for 2.4 GHz and 5 GHz from most people) that's what I recommend trying to locate, since, IMHO, 900 MHz is better because it doesn't interfere with wireless networking, and has better range through walls and such.
EDIT: Yes, people with scanners can listen in on that phone. It's an analog phone, so all they need to do is tune in. The same is true of all cheap 900 MHz and 2.4 GHz analog phones.
