price a bit subjective....
but you can do this comparative..
in order to get a gps with 3d imege inside such as buiding:
Garmin new model cost around RM1K++, other brand only RM700++

i suggest find gps with large screen...
but be aware that the battery wont last long...

here come Garmin advantage, garmin can operate more that 2 hour with full setting..
but u use in car right, just plug the charger...
heh...
