Though I like the T4, your best bet I think would be a T3, either the "regular" model (with removable accessory shoe) or the T3N, whose accessory shoe is permanently attached. Much better made than the later, smaller, plasticky cameras.
Either will work without batteries, though of course the meter requires batteries -- 2 x 675, which are mercury (1.35V) -- or use zinc-air 675 hearing aid batteries. Or, just use 357 1.5V batteries, which last a long time and are easily available, and cut the film speed in half -- ISO 200 with 400 speed film, for instance.
Make sure the meter works -- a lot of these have dead meters, for some reason.
