I have owned the S2, S3, S4 and SP. The ones I liked the best always were the S3 and the S4. The S3 because of the frame lines (useful lenses) and the S4 because of its simplicity. I used to like my S2, but the fact that only had 5cm frame lines and a funky shutter speed dial always drove me to desperation. Besides, there's the thing that you cannot change shutter speeds once the shutter has been cocked... So, I am happy with the other camera bodies and recommend them warmly.
BTW, the S4 on sale is mine.
That you cannot change the speed on an S2 when the shutter is cocked, is nonsense. Of course you can. Cocked or not, you can always change the speed, in a very convenient way.
That the S2 has only frames for 50mm is an advantage. If you see more than one set of frames in the viewfinder at the same time, you should always check which one to use. That is extremely irritating. That's the big mistake on the S3 and the SP. The best is the viewfinder of the Leica M2 that always shows only one frame. The S2 always indicates only one frame, 50mm. The chance of making a mistake is therefore much smaller than on an SP or S3.
