? Not really to my tastes, and not cheap enough, but (IMO) a pretty good deal.
I'm with JimLee: there have been lots of AVR development boards before and after Arduino, with lots of additional features. For one reason or another, none has received the acceptance of the Arduino. Prior to Arduino, the "AVR Butterfly" was probably the closest thing; there were a bunch of nice tutorials written about it. But when you look at trying to use it beyond the tutorials, it turns out that nearly all the pins are already connected to something, making it a bit of a pain to use.
