Thanks, but yes I have bought (and do buy) from Mouser and TME and from Farnell and CPC and RS and mini circuits, we are lucky in the UK to have a lot of choice now compared with say ten years ago, but as I'm not a company (it is hobby electronics) I have to pay the VAT. Digikey tend to be the cheapest out of these and have the most extensive range together with free next-day delivery as long as I reach the threshold - the thing to be careful of is ebay as components on there are often much more expensive than say Farnell - in fact various rather dodgy sellers seem to sell Farnell stuff at a 40% mark up on ebay, I'm not sure how they get away with it.
