The only HP camera I really liked was the 618, but mine grew legs and walked away
. Never used an Olympus.
The Canon A75 is a great camera for the price (I'd say best bang for your buck around) - If you're looking for larger images the Canon A80 is also a good camera. The Canon S1 IS is more or less an A75 with a 38-380mm (35mm equivalant) image stabilized lens on it which can be handy if you're looking for more zoom.
BTW: the S1 IS doesn't have an auto-focus assist lamp on it, but both the A75 and A80 do. If you're thinking of taking pics in low light conditions I'd make sure the camera you pick has one.
