Out of the box, the Olympus SP350 is one of the few compacts that support RAW. Also have a look at the Olympus SP550. I’m not sure if the 350 is still available - it doesn’t appear on Oly’s site in Australia (which is relevant for me, but probably not for you!).
If you are feeling brave you could consider a camera that doesn’t support RAW out of the box, but has been hacked. There are a number of hacks available on the net, that give cameras like the Canon Powershot A640 RAW capability. Of course, the manufacturer does not support them, and it probably invalidates your warranty. Let the user beware..!
As to fast (i.e. low shutter lag), I am yet to be convinced of much difference between cameras. I have used an Olympus Stylus 400, Sony DCR-P150, Canon Powershot A85 and a Canon Powershot S70 underwater, and frankly, I couldn’t tell you which camera has the lowest shutter lag. If you habitually pre-focus your shot, I think any differences are beyond human detection. I have noticed differences in the time cameras take to focus though. Out of the cameras I have used, I have found the Canon’s the quickest and most consistent at focussing, with the Olympus second, and the Sony the slowest / least effective.
Just my 4c worth!
