Galaxy Mini @ 7600 Pros: Good Ram. Cons : QVGA 3.2 MP
The order i have mentioned is my personal order of preference
Avoid Karbonn A1, Spice mi 310, mi270, Micromax a60..
You can go for Spice mi350 and Lava S12, if u research a bit.. Actually the lava looks cool but 5 mp Fixed focus camera is a deal breaker for me
