I'm sure most will already be familiar with this company - but I thought this might benefit someone.
I've just received their hard copy catalogue - and it is so helpful having the option to browse in the old fashioned way - particularly if you're not familiar with some of the more esoteric component names.
I've no connection with this company, and I'm well aware that there are others too, but to date I've found them very helpful.
