I was looking for something similar and bought a used Powershot S90 from eBay for $200 or so. It's basically everything the S95 or S100 are, minus a bell and whistle here and there. The S90 gets wonderful reviews, it has a fast f2.0 lens (at least at wide angle) is made of very solid feeling metal, and take extremely high quality images. It also shoots in RAW mode.
