Check out the Olimex site for inexpensive ARM-based development boards 
and programming tools:

http://www.olimex.com/dev/index.html

I'm not sure if you can buy direct from them, but they have distributors 
  - in the US SparkFun sells a lot of their stuff at reasonable prices.

You can of course buy boards from other outfits too. Most of the 
development tool vendors (Keil, IAR, etc) provide boards but they're 
usually much more expensive.

Karl gave a good list. The Olimex page gives a fairly comprehensive 
overview of the silicon vendors out there too. I've used parts from ST, 
Analog Devices, Atmel and Philips/NXP. I especially like  the Atmel 
SAM7S parts for SDIY stuff because they have an I2S port, as well as a 
USB port.
