Not shamelessly promoting some company. The company actually pisses me off because they have insane shipping prices and a $5 handling free for orders under $30.
But! Their protoshield is pretty nice.

It has:
* An xbee socket (which is important to me and is the only thing missing from the Maple to make the first wireless Armduino)
* Servo ports with selectable VCC or VIN power source, important since the Maple is 3.3v.
* Breakout for 32pin dip
* Extra Buttons, hopefully to adapt to the boot button in the bootloader
* Typical Protoboard features.
Alas, it blocks the 18 pin header, as most shields will do. I'm getting risers and, optionally, a screw shield ( http://www.hvwtech.com/products_view.asp?ProductID=1197 ) to gain access to the header. I would like to suggest, however, that there be an option not to have the header populated so an angled socket could be added or so it can be broken out on the bottom.
