6D

[JerryLove]

No typo error - 6D + 24-105 f4 is twice 70D + kit lens (not worth mentioning)

Actually the STM lens on the 70D isn't at all bad and is excellent for video work.

$2888 is well above market for a 6D with 24-105 f/4L. You should not buy that from whomever is selling it. You should be able to get that same camera and lens, new, from a Canon dealer (BHPhoto, KEH, Amazon) for between $1900 and $2300.
