An Olimex board with NXP ARM7 MCUs, free GCC compiler and cheap JTAG programmer may be a better option if you go that route (non-Microchip). I think Butterfly and EZ430 are bit too limited in terms of expansion. And PIC24 has an architecture as nice as AVR and MSP430. ARM7, AVR and MSP430 are all supported by free GCC compiler. PIC24 is also supported by GCC based C30. C30 is supported by Microchip so it does have an edge. The free student version has no code size limit (only optimization limit).
