None of these kit is expensive. I assume this is for home or hobby use?

There are the IAR boards with JTAG and eval compiler... similar to the Keil but the compiler has a 32K limit.

However both the Keil and the IAR compilers are vastly more efficient than the GNu unless you have hours to spend optimising your own version to get it closer.

Yes, but why do you need one? The vast majority of embedded systems don't use an RTOS.

What optimizations do you mean?

Depending what you mean by low-cost, the rowley offering looks to be good value for money. available for both windows and linux.

With a wiggler clone (easy to build) together with OCdemon and insight you can debug programs in RAM. Not to sure how good this combination is for debugging code directly in flash.

There are quite a few RTOSes available, from free to fairly expensive. If you google for ARM RTOS you should get quite a number of hits.

As someone else suggested, join the lpc2000 group on yahoo.
