Atmel has a promotion going where they're selling the STK500 plus the Dragon together for $49. I'd been planning on buying a single STK500 for $79, so I was pretty blown away and I ended up buying two of these bundles from Digi-Key yesterday. So, if my brain didn't explode, I could work on 4 projects at once.
Apparently, this hasn't been promoted aggressively yet. I was actually the very first person to buy this bundle.
I suppose this means a new dev board could be in the works and Atmel is trying to dump their stock of the current boards.
