Hi Paul,

my name indicates that I am a little biased ;-)
For floating point it helps a lot to have a 32-bit architecture at a
similar price. Hope I won'y get banned for helping somebody out here.

A little faster could be an ARM7 running at up to 60 MHz like the
LPC2000 family from Philips. If you go for the low end of these
devices, e.g. LPC2132 or LPC2131, you will get 32k or 64k flash with
8k RAM and much better performance. 
Info here:
http://www.semiconductors.philips.com/cgi-bin/pldb/pip/LPC2131FBD64.html

As for affordable tools, fully supported by GNU http://www.gnuarm.com,
the LPC2130 board from http://www.keil.com/mcb2130/ has a 16k compiler
coming with it. There is a free 32k compiler from IAR but I don't know
how to get it except with a "kickstart kit" which includes a different
chip LPC2106.
Both evaluation boards including the 16k / 32k compilers are $149. You
can get more information on the tools here: http://www.lpctools.com
Other lower cost C-compilers are available from Rowleys or
http://www.imagecraft.com
http://www.rowley.co.uk/
Other low cost boards if you go for the Rowley compiler would be from
Olimex who also does low cost boards for AVR offers ARM boards too.

Hth, Bob
