T3i camera owner here, let me tell you... a t3i by itself isn't an effective tool. You'll have to invest in additional equipment, such as a professional lens, tripod, stabilizer, extra batteries, and lights to truly get professional video. That said, there really isn't another out of the box option that I know of, that comes with manunal controls for video. There are some great sony camcorders though, such as the sony cx900 or the ax100, great camcorders for their reasonably great prices.
I hope this helps out.
