Yeah. I was thinking about the AVRisp, my project will be using dozens of ATTiny85's. The first test ones, I just used ArduinoISP and wired it up to one of my Unos. But for $5 in parts (probably less, actually) I can wire it up as a shield with a nice socket for the chip to be programmed. They're all getting blasted with the same code. ArduinoISP should be plenty adequate. I'll also be using a lot of Nanos, but I've found a nice source of bulk packages that come without the header pins soldered on - that takes a few seconds per board, and then they too get blasted with the standard code for that part of the project and are ready to plug in and go.
