Some other titles claim to provide this - but none do it better than Vegas. For $499.00 you can get Vegas - which is perfect for multiple camera synchronized editing. It's easy to learn, and provides you with unlimited DV editing power, including unrivaled real-time previewing of all your edits without needing expensive hardware acceleration. I routinely edit music videos with six different camera angles and a separate audio mix - all synchronized on the timeline. All my cuts/crossfades, titles, effects, etc. are available for real-time preview without having to render.
If you're eligible for a student scholastic discount, you can get it for under $200.00. Believe me, a $500 investment will get you the last editor you'll ever have to buy. You'll be rivaling (and in some functions, exceeding) the so-called "heavies" Premiere and FCP4, for 1/2 the price. And, you'll probably not have to beef up your computer to run it.
