Around here, USA if I want a ARM to proto with I just go on the net and
look for a board with the desired arm on it  I bought one recently for
$150 and the config was ARM9, 64meg ram, built in 256mb of flash with
linux in it and the usual USB, Ethernet and an IO extension area.
Plug in a USB flash of 16gb and you can bootstrap develop on it.

Generally a decent P4 PC running linux makes a good development
system as tools for arms are common and plenty of free stuff out there
and linux for ARM (if you need a OS platform).

I've seen boards in the 80$(US) to 300$us range.  Generally you
proto starting with that until the memory requirements are known
and then design a board (or even ask the proto vendor to do a custom
if its a volume build).
