Why don't create a own development board? :-) Made for Atmel Mega16/32. Includes 10-pin-plugs and clamps for every pin/port on these uC. Input voltage is ~7-16V i guess, regulated to 5V and 3.3V. Selectable voltage (5 or 3.3V) on the 10-pin-plugs and the clamps. There is also an ft232RL and a USB connector included to connect your PC to the uC easily.
