inspite being a sony fanboy(self declared) i would like to agree wid what akshay said,,,coz though w205 and w395 are in those range,they being licensed sagem devices and sagem platform,,cannot be modded(though u will get walkman 2.0),but whats the fun of sony ericsson without modding it,
if u do not care bout bluetooth,u can try out w200,,though archaic now,,but it still has its charm,and good sound too,,and is fairlymoddable(atleast u can mod acoustics and flash menus,though for the cam,the least said,the better)
and for Akshay,dude can u help me out to find a complete new fascia 9 keypad set for my C510,coz i have the silver one and is a bit worn out,,would like to have the complete balck one,,BUT ebay seems to have none,,also our local sony service centre
