Biggest buffer on a sub £500 DSLR

[agour]

Hey guys,

I'm going to purchase a camera as a backup to my main 6D. I'm going to stick to Canon for obvious reasons, but I'm just deciding what model to go with...

Essentially I'm just after decent image quality, and a really high buffer/write speed. I'd love to be able to take 2-3 frames per second, and shoot indefinitely. Ideally with full RAWs, but m-raw would also work.

I checked the raw video chart at http://www.magiclantern.fm/forum/index.php?topic=6215.0 and it lists the buffer sizes.. but honestly I'm not sure what the numbers mean?

Anyway current options are a 7D, 50D, 5Dc, or I might even be able to stretch to a 5D2 (but I'd prefer not to).

Does anyone have an idea if any of those cameras are capable of a constant 2-3fps?

Cheers

For photography? The 60D seems to have a huge buffer, but the 50D shoots a bit faster (and you're looking at about 600 used vs 300 used - I got mine from a photographer I work with for $200 :3 ).
