This may not be the kind of thing you're looking for; but you should be able to get one around your price range, the lenses are sharp and I think you can still get them serviced. (But I'd look into the before buying one, if it's a concern.)
Contax G series. They use Carl Zeiss T* lenses, have automatic or manual control for exposure, and the 45mm lens is f2.
I'm sure others here will have suggestions perhaps better suited to the p&s description; I know there are fans here of the XA, but I have no experience with those.
