i have two favourites: www.komplett.co.uk = cheap, good range of stock, fast delivery, easy to deal with. They seem to keep more stock than most, so it can be a good place to find older parts, as well. www.dabs.com = cheap-ish, good range of stock, generally have what you need, but can be hard to get good service when something isn't right.
I am mighty pissed off. I took your links put them all together with mine and posted them in the "useful links/music production" section and they disappeared. I've now done it again - see how long they stay there this time.
Anyway, I ended up using good old dabs. Best price and they're already on the way.
