I have tried nokia and motorola before my samsung N 620.
The 16 bit tones sound nice, you can have ringtones long enough to go on for 3 minutes (perhaps more) , can load new 16 bit tones using a data cable connected to a computer.
Antenna provided good signal strength, is smaller than other phones in the same price range.
Good buy if you are upgrading from Samsung 220, NOKIA 33XX, motorola talkabout series etc. :)
