Ok, I just got a Canon powershot A40 from amazon where it is on offer for 200
quid atm (rrp 260). Takes AA batteries which is a + but you will most likely 
want to get a NiMH charger which will be around 20 quid including batteries. 
The camera is about the same size as a medium sized 35mm compact but quite 
heavy as it has 4AAs in it. Oh also the A40 allows you to add a wide angle 
lens adaptor (24mm equiv) and also a telephoto adaptor (300mm i think) which 
are about 80 quid each so it is nice and flexible.

Main problem at the moment is to make it work under Linux I will need to modify
part of the source for gphoto but then it is the case of adding the USB id so I
guess support will be coming soon in gphoto. Of course you could always get a
USB compact flash reader and do it that way.

The camera also does exposure compensation and lets you set shutter manually
and apeture but this is fixed at either f2.8-45 and f8-14 at 35mm and 105mm
respectively, oh and it has a macro mode.

the canon A40 does ISO 50 - 100 - 200 and 400.

35 - 105 mm equivalent

jpg on mine.

smart media or compact flash, i just bought 128Mb of compact flash that will do
about 128 1600x1200 pictures on it for about 35 quid as the supplied 8Mb is a
bit useless.

Amazon for the A40 at the moment as i havn't seen it cheaper than 200 quid.
