farnell are by far and away the cheapest on most things and free delivery (which if you are like me you forget stuff is a major plus... I've had 4 orders delivered next day from them this last week, each of about 2 - 3 quid...). I have compared Rapid, Farnell, RS, Maplins, CPC and few others like Crickelwood Electronics and farnell have come out best onmost projects and have the biggest range.
