Hi Guys,
In Belgium we need a TVA-number to buy at Farnell. I buy my components in Germany. www.conrad.de
prices are more then acceptable. 
There's a www.conrad.com too, for the UK, and in France, and the netherlands. However, I found out that Germany is the cheapest and if you group orders... it's worth paying the extra for transport.
Don't know if getting them to Scotland is possible.
bye

These are readily available, farnell have loads of them @ 8p each. 

Sorry to kick you in the shins with this little note, I could have 
also got them as samples from the manufacturer.

If there is any thing you want and you hav'nt got an account, let me 
know and an arangement could be set up.
