I can't recommend warmly enough the Discovery board from STM.
It sports a Cortex ARM M4F that can run at 180 MHz, has a native
IEEE compliant floating point core, 2MB flash and 256 kB RAM,
and a wealth of interesting peripherals on chip, TFT display touch
enabled included.  And at 23.52 USD is cheaper than a much
less powerful Arduino...

I implemented on it a fully featured SDR, without using any opsys,
talking directly to the bare metal using the Keil IDE/compiler.
A joy to use. Look here :
