Tablets are the obvious choice.  If you won't be using the wireless
capabilities, you can find a few vendors who will have most of the
drivers available for you (assuming you are not willing to run
under the native OS).

Your quantity sits in that large "bad spot" between "just a few"
(that you could scrounge from other applications) and "a good
size run" (that a larger vendor would be willing to produce
economically).

There are, also, some "surplus" vendors you can approach for
one time buys (i.e., they probably will *never* have the same
particular model available again) -- but, you're stuck with
whatever they happen to have on hand at the time.

Here (prototype quantities), I opted for some surplus PDAs to
fit that role (4" dia) with BT & WiFi to give me the connectivity
I needed (I wanted a handheld solution).

You might also consider non-visual interaction (I opted for haptic
and speech) as this is often less expensive and more "available".
