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.
