Ray,
People fall in love with their editing software, so whoever you ask is going to recommend the one they use.
I too began with Pinnacle Studio [8] software. I didn't care for Vegas, but that's just my opinion. Honestly, I didn't give it much of a chance, maybe an hour or two. I switched to Premiere Pro 6.5 then upgraded to 2.0.
I also use the Adobe Encore, Audition, Photoshop, After Effects software (varying versions) and am saving up to pop for the whole two thousand dollar software suite.
