well, till now, Canon machine were tested and about some models u can find in the forum some reports and experiences.
Canon supported bu David. But take in mind that till now, you can use the models that support the liveview mode, coz autoshooting function (at full resolution of camera) not available now, but in the future it will be.
I succesfully use an EOS 1000D, that also is quite cheap.
