Looking for a 3M camera

Hi
I am looking to buy a new 3M camera, I have narrowed
the field down to Kodak DX6340, Olympus C3300,
Finepix A310 or Pentax 33LF.

I have just bought a Minolta Z1, I only bought it
because it had a 10x zoom, but then realised it wont
fit in my pocket and the pictures are not that great.

I need a camera that has a good macro lens
and good low light capability. Im not worried
about loads of manual features, point and shoot
is fine for me as long as the results are clear
and sharp. My favourite so far seems
to be the Olympus and the Pentax second, that's
just going on reviews on the net.
My budget is £250 can you recommend
any of the above cameras?

Thanks in advance
