I think that's changing. I've seen explicit aperture settings on $400
consumer-grade digital cameras.

Every digital camera has the capability to do multiple apertures -- the trick
is coaxing the camera into doing what you want if there isn't a way to set the
aperture manually. There's always a way... :-)
If you don't have a manual aperture setting, you can still get a medium
aperture like f/5.6 or f/11 (well, probably not f/11 on a cheap camera,
but certainly f/5.6 on any point & shoot, anyway) by simply putting the
camera in to "auto" mode and throwing lots of light on the subject. The
more light there is, the smaller the aperture the camera will choose. And
if you're lucky, your camera might just even write the aperture to in the
EXIF block of the JPEG file. :-)
