The Freescale Tower system is pretty cool in that you can choose from 
amongst a family of microcontrollers to work with the various IO boards, 
but you can also get a breadboard to plug in, so you can set up your 
own. Haven't had time to play with mine yet, but the configuration with 
the Kinetis ARM device & CODEC board is perfect for me, as it saves me 
the hardware prototyping of a simple audio processor design I have in mind.

An alternative to the Tower system for ARM is the Kinetis KwikStik, 
which is an all-in-one, with programmer, LCD & stuff. (Doesn't have the 
I2S audio CODEC of the Tower add on board though. Unless you plug the 
KwikStick into a Tower, which is a possibility.)

Just a note that if you use Freescale's design tools, whilst the free 
version of the Eclipse-based CodeWarrior is code-size restricted, it's a 
pretty respectable code size, and I'm given to understand that a 
previous limit on the number of files allowed in a build no longer exists.

Both the ARM Tower modules and KwikStik have example applications ready 
to load as CodeWarrior projects but, sadly, these are Windows only as 
whilst Codewarrior has been ported over to Linux, Freescale's MQX RTOS 
tools still has to be installed as Windows executables. So I'll be 
starting from scratch, which won't be quite as easy, as I won't have all 
the hardware mapped out for me.
