hye guys.need some opinions here.i've been using htc touch diamond 2 for nearly 2 years,and thinking of changing phone to android.between samsung galaxy mini and htc aria,which one do you guys prefer?as i preference games and gps..?

my budget is around 700 and below.as i tends to look for 2nd hp but still have warranty.so you would not recommend either htc aria or samsung galaxy mini isn't it?then what about wildfire?i really noob about android,but i don't mind starting with 'cikai' one .
