I'll second Eric's vote: AVR XMEGA is good stuff. I has an instruction set architecture and peripheral mix that isn't completely schizophrenic (I'm looking at you, Microchip). And the gcc support is excellent, both standalone and via AVR Studio.
I use the AVR Dragon adapter to debugWIRE, but I have played with avrdude and been pretty satisfied too. b.g.
