I'd go with whichever is cheaper. I haven't had any card problems, and 512MB is not that huge. Now if you were saying two 512MBs vs one 1GB, then maybe I'd say two 512s for sure.
Anyway, your C-50 uses xD Picture Card as I recall, and I don't know if you can yet get one 512MB card for cheaper than two 256MB cards. So I'd simply go with whichever costs less at this point in time.
