For those brave enough to etch a board, Gen7-ARM exists. Very affordable, but also work in progress. 48 MHz and of course 32-bit. One of @bobc's(!) printers is running it. For partial instructions, see [www.reprap.org]
If you want to make one, I'll send you design files. Not public, yet, because RepRappers have the habit to expect everything to be finished which is found on a server somewhere.
