Check out this <a href="http://www.dpreview.com/reviews/canons40/
" target="_blank">review of the PowerShot S40</a> at DP Review. The S40 is basically a shrunk down version of the prosumer G2. It has 4MP, so your files will be twice as big, but you'll also have twice the resolution for scaling and cropping. It won't have the accessory lenses of the A40, but will have higher picture quality due to higher resolution.Mandricard:
I have to admit that in this day and age, 2MP like in the A40 may be on the low end if you want to print a lot of 8x10s and larger pictures. The S30 or S40 would definitely give you a resolution edge. Especially for someone like you, who is used to dealing with gargantuan image files, more pixels (i.e. 3-4MP) may be an important factor. But if you just want to take pictures for the web, a 2MP will be more than enough.

A set of 4 AA NiMH rechargeables with a good charger will cost you about $30-50. Check out <a href="http://www.greenbatteries.com
</a> for example. If your camera uses proprietary batteries, you'll probably have to spend more. Even if your camera comes with one battery pack and a charger, you'll have to buy a second battery (a) because you wont be able to use AAs in a pinch and (b) because most proprietary batteries have lower capacity than a set of AAs (and you don't want to run out of juice when the bride kisses the groom or the crocodile bites the hunter).
The cost of memory cards will depend on the kind used (Compact Flash, Memory Stick or Smart Media). CF is still the cheapest per MB. You can easily get good cards for less than 50c/MB, e.g. a 128MB CF card for $60. That's why I excluded non-CF compatible cameras very quickly in my search. Note, however, that memory prices are falling precipitously for all flash memory formats.
Obviously, the larger the card, the more pictures it will hold. I went all out and got a 128MB card even though they were still well above $100 at the time. But I never regreted the investment because I could take close to 140 images at the highest resolution and lowest compression with my 2MP A20. It's nice not to have to select and delete pictures in the field. It is sometimes difficult to tell whether the autofocus did a good job on your camera's tiny LCD.
In conclusion, I believe that any $4-500 camera you get now will have a hard time satisfying you in the long run. (I remember what you told me last Spring about the low quality of dital camera images compared to scans from film.) So as long as you don't get any of the cheap entry-level cameras, you should be fine.
