I've built a couple of projects using an Arduino clone.  Very easy to get
working, there's a complete IDE available and it's pretty simple to set
up a standard "make" environment if that's your preference.  I'm rather
sold on these.

I recently picked up a couple of TI LM4F120 evaluation kits.  These were
$5 each INCLUDING SHIPPING.  There's a free gcc based toolchain for
those too.

If you don't like C, you can use a Basic Stamp.  They've been around
a long while.
