t3i there footage is so crisp its amazing. Tapes are a pain in the ass, and VX's break. T3i's bearly brake.
Also, get the t2i, only difference is a lcd thats moveable.
And Filming over the same tape degrades the quality, and also puts wear on your heads.
the only problem i have is i would need the t3i for the flip out screen, and its 900 bucks, where the vx2100 is 500
