I recently purchased an HP Photosmart 435 digital camera. I'm
looking for an A/C adapter that is less expensive than that made
by HP, which costs ~$50 (the camera itself was only ~$100, and I'm
not necessarily going to get another HP camera).

The power requirements for the camera, via A/C adapter, are listed
as 3.3 to 3.7V and 2500mA. I haven't been able to find a generic
adapter that matches those specs.

The closest that Radio Shack seems to have, of their standard,
non-adjustable adapters, is 3V and 500mA. This adapter system has
the advantage of a wide array of tips, the smallest of which (female,
0.7mm interior diameter) would seem to fit the HP camera.

While 3V seems too low, I wonder how the camera is able to make do
with two 1.5V batteries as a power supply!

A Radio Shack universal adapter, which I didn't see, would, based
on the one I have for a radio, have 3, 4.5, 6, etc. volts, which
seems not close enough; and it probably wouldn't give the correct
amperage.

Digi-Key's catalog has a wider range of voltage and amperage choices,
but only matching the voltage, not the amperage. Also, I don't
see a standard tip for them that is small enough for the camera.
A custom-made tip, which they offer, would possibly bring the cost
to where I might as well buy HP's version.

There's always the possibility of a jury-rigged device, but I'm
trying to avoid something that messy.

What substitutions are possible under the circumstances?
