I am playing with the free version of IAR but for home project work the full up program is too expensive.
I know about GNU ARM but I have been told that the free tools are not as easy to use as the $IDE tools. I have went through the free GNU ARM tutorial, very good by the way.
I might be able to swing the Image Craft package if it's good. How does it compair to the ohter guys?

I've been pretty happy with it, although to be honest I've lately been doing mostly AVR development. The ARM stuff is contingency and getting me ready for when an ARM is the appropriate fit. That said, the ARM and AVR (and the rest of the packages) all share a common GUI and compiler front-end.
I usually code with gvim (outside of the IDE) and use the GUI mostly as a push-button make. The "application builder" is handy for getting the basic skeleton of an app set up, handling the grunt work of initializing the various peripherals and interrupt service routines.
I'm happy enough with them that I've purchased their ARM, AVR, and MSP430 compilers but rather than going into a long exposition here I'd recommend dropping by their mailing list archives at

As usual, most of the discussions are started by people with problems/issues so it's a good place to sample what questions there are and how well (or not) the questions are addressed. It's generally a pretty chummy group, which is a good sign. The AVR list is much more active then the ARM so you might want to check it, as well, to get a feel for things.

Hi David,
Like Rich, I have used the Imagecraft AVR compiler for more than four years and cannot fault it. The tech support is second to none and if bugs are uncovered they are fixed rapidly. All Imagecraft compilers are fully functional for 30 days and then become code limited unless you register. Best value for money that I know of.
Developing embedded projects/products usually has 4 constraints.
What you need/want the achieve
time
cost
quality.
If little money and lots of time then GNU GCC complier and GNU GDB Debugger should be considered. There are a couple of Open Source Compliers that can be bundled with an IDE (Programmers Notepad, Code::Blocks, Eclipse etc).
The GNU compiler is typically operated by command line arguments but an IDE puts it all together - and allows button click operation. The GUN GCC ARM Compiler is reasonably mature
Most ARM processors have JTAG debugging as standard - So it is a good idea to consider debugger h/w and s/w also.
From what I understand Image Craft is Complier & IDE only
Kiel and IAR offer a more complete package IDEs that operate Compiler, Simulator, Debugger, Micro programming software.
Don't forget ARM and Green Hill Tool Chains as well.
While most Compliers have an optimisation option - Green Hills can show the optimisation in a graphical sense - for cases where you need to squeeze the most amount of code in to the smallest amount of memory. For high volume projects - the size of the memory can make or break the product success and price point.
So - as in life - you get what you pay for.... although some "donations" to GNU software development etc is very much appreciated.
There are many ARM processor manufacturers and more jumping on the band wagon - so an investment in tools will allow you to swing accross many ARM manufacturers.
With AVR tools - only for ATMEL With ARM7 tools - Sharp, OKI, TI, Philips, AD, ST INTEL and many others .
With 80c51 tools - Over 30 manufacturers - may be many more.
We have a number of potential solutions we are looking into. Currently any ELF/DWARF capable debugger (meaning all of the ARM debuggers) should work with our compiler output though. // richard

Already said by someone else, but I definitively vote for Rowley's "Crossworks For ARM" gcc-based toolchain : reasonnably priced, clear and powerful IDE, good debugger and simulator, low cost JTAG probes as options, good support, good support libraries (including a small free RTOS that I've not used), numerous examples, etc.
PS : I don't work for them, I'm just an happy customer ;+)
Friendly yours,
