Search this forum and you will find over the years many people have pained over this choice of "Your First Rig"

Some advice comes from top dog hollywood operators, and other advice comes from the manufactures/designers. Still yet you can find insight from others who are recently getting into steadicam as well.
That said, I just read this quote, and thinking back you my start into this world of steadicam, I feel it holds true here too.
