Maybe no one here needs an AVR programmer/developer board, but at $6.52 (free ship from HK), this kit is worth it just for the price of the parts. Even if you toss the PCB, there is a ZIF socket and numerous connectors, headers, caps, crystal, switches, LEDs...
Heck, even just build the kit for soldering practice. ..
"When you make a thing, a thing that is new, it is so complicated making it that it is bound to be ugly. But those that make it after you, they don’t have to worry about making it. And they can make it pretty, and so everybody can like it when others make it after you."
