There was the papilio duo too which had the Spartan 6 LX9 FPGA with an ATmega32U4 on the bottom. Not sure if they are for sale anymore though. I backed the kickstarter (and work with a company which made some of the wings for them) but I never really got into using them. I still have mine around and plan on using it for some project in the future though.
