You can buy a compatible avr, download their open source whatzamawhozits, and roll yer own. It's what I do.
Somewhere around here is a kade-compatible avr vendor list - I'll see if I can find it. As for the rolling your own bit, scott or somebody has a handy guide. I think it's in scott's sig. In fact it might all be in scott's sig.
Lemme summon scott...

Here's the current situation.
- MaxRod has connections with the guys who make the Minimus boards and mentioned
here that has some for sale.
Right now, he is the only source selling them AFAIK.
- Kevin (sharpfork) runs the official KADE store, but I think he's
still working on the miniConsole+ Kickstarter rewards.
Until he finishes those, I don't expect that he will fix the
emukade.com site and restock the
North American store.
- Bruno and I are getting close to a beta release of the new miniArcade 2.0 Mapper.
It includes features and documentation that make it much easier for people who want to "roll their own".
All "DFU" bootloader boards like the
MT-DB-U4 should work directly with Mapper.
For other bootloaders, you need to use other software to load a HEX firmware and EEPROM file to your 32u4 board.
