Thanks a lot everyone for the great help!
Here's what I want it for, what I like now, and what I expect...
I have been using an XA sometimes, and first I decided to use it for sun. I decided it because I don't like to focus with it, so for sun I can easily keep it prefocused at f/8 - f/11 and make it a point and shoot especially for fast shooting in dangerous places.
Then I tried to find something that small but with higher ISO settings for doing the same in overcast or even lower light with ISO 3200 film... But it was impossible: not only were the options close in price to modern Bessas, but they were bigger and many times less capable than the XA or my Bessas... So it didn't make sense...
So, I decided to forget about ISO 3200 and just use the ISO 800 available on my XA for overcast (ISO 1600 XA's lack aperture control). Anyway with ISO 800 in overcast or shadows I can prefocus and stop down a bit if light is not too low...
Then I thought I should buy another XA so I could use them at the same time (sunny/dark sides of the street...). But then I remembered what a huge amount of any camera I waste for that kind of shooting under the sun: I don't need AE and I don't need to meter because I know the settings for any film, I don't need a rangefinder because I prefocus, I don't need to change lenses because I just use a normal wide... All I need is being unobtrusive and setting aperture and speed. I could even use a fixed speed camera...
That's why I thought maybe someone did a very small camera... But again it looks like there's nothing as small as the XA...
Why did I prefer thinking of another camera and not the XA? Because the XA is AE only, and If I shoot someone leaning on a wide white wall, or someone dressed in black in a dark environment, my exposures are off, especially if I am pushing, what I do to use the ISO 800 setting...
Well, once again it seems the XA has no rival for size and unobtrusiveness... Looks like I'll have to get a second one and trust its metering... Most other cameras are bulkier, and many times silver... I tend to feel my XA and even my black Bessas with the flat 28 look more like a toy, and that's what I need... Even the Olympus RC and the Rollei 35 SE make people look at them more...
Thanks!
Cheers,
Juan
