Yes, this man was fabulous. Recently I’ve taken (parts of) two of his speeches to heart:

We shall go on to the end, we shall fight in France, we shall fight on the seas and oceans, we shall fight with growing confidence and growing strength in the air, we shall defend our Island, whatever the cost may be, we shall fight on the beaches, we shall fight on the landing grounds, we shall fight in the fields and in the streets, we shall fight in the hills; we shall never surrender, and even if, which I do not for a moment believe, this Island or a large part of it were subjugated and starving, then our Empire beyond the seas, armed and guarded by the British Fleet, would carry on the struggle, until, in God’s good time, the New World, with all its power and might, steps forth to the rescue and the liberation of the old.

never give in, never give in, never, never, never, never-in nothing, great or small, large or petty – never give in except to convictions of honour and good sense. Never yield to force; never yield to the apparently overwhelming might of the enemy.

You ask, what is our aim? I can answer in one word: It is victory, victory at all costs, victory in spite of all terror, victory, however long and hard the road may be; for without victory, there is no survival.

The Churchill centre has quite a few of his speeches and quotes in text form.

Earthstation1 has them in audio form – magnificent and powerfull stuff from IMHO one of the greatest statesmen of all time. (but in real audio format)

Freeinfo society has a great collection of a whole load of mp3 versions of great speeches made through time.
