I was lucky enough to get my hands on a Lunt 60mm B1200 (blocking filter) 'scope that'll get here on Friday. I spoke on the phone with the main guy at OPT when I ordered and he said he'd been using his Canon 5DMkII camera, unmodified, perfectly fine with Lunt 'scopes for the past two years. So, my 7D he said should be fine, but what he really recommends is the modified webcams like the DMK 51AU02. Only he was out of stock on those.
My on-campus observatory has a spare DBK 41AU02 color that they said I could use, but speaking with the main guy there, he was saying that the Imaging Source cams are only 8-bit, which he personally doesn't like.
Fleas aren't. And, the Flea3 14S3M model, at least according to this FOV calculator, will see the entire sun due to its 1/2" chip. It's also 16-bit. Or, there's the 20S4M models that use the same chip as the DMK 51AU02 does (and would also see the whole solar disk).
