My modest redesign of the LUFA powered AVRISP MKII project. No firmware changes needed. Uses 2mm and 1.27mm pin headers (primarily what I use on my own boards ), can reset or enter DFU mode using a single reset button, and has an ISP header specifically for burning new boot loaders.

It also has a USB-B connector AND a micro usb connector. Because I always seem to have only the wrong USB cables on hand.
