That was, not suprisingly, the first place I looked. Alas the web site is
somwhat broken, in that if you look at microcotnrollers it will tell you
that there are<n> of them (for a large<n>) and then ask you to refine
the sarach by selecting from checklists. It's then that you discover that
while you can select DIP, PLCC, PQFP, SIOC, BGA, etc packages, the sum of
the numbers for all the package types is a lot less than<n>. And you
can't seay 'I definetely do not want a BGA deivce).
Mind you, the paper catalogue is not much better...

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).
