Which phone is best for me? SE C903 or SE W995?

im 15 yrs old. i hav an ipod so im not buying the phone for the music player - im buying it for the camera (and the texts). im not rich but the c903 is �20p/m and the w995 is �25p/m so there is not much difference. i want something to last; to be good to hold; and can stand a bit of wear and tear...(remember im a 15yr old!); to be easy to use; but mainly i want it to be a GOOD CAMERA (but im also wary about the price - for that reason i cant get it on payg cos i will hav to top up each month anyway cos i do LOTS of txting) but remember its for a 15 YR OLD......also the only contract i can get the C903 black is on Three Mobile and apparently....they're not the best coverage...to put it kindly! (wheareas the w995 is on vodafone which is good) thanks
