After you sent me the PM about looking in to buying a steady-cam and seeing your other points I am a little confused. It seems like you are saying that you are interested in directing, editing, DOP and steady cam work as well. I just thought I would mention a few things I have noticed. To be good at everything you mention would be very hard. I currently work as a Director/shooter and splitting thoughts to do a good job at both is a real challenge. I have met a lot of people who do multiple jobs but your choices are very spread out. In fact I personally have never even met a single Steady-cam/DOP guy. The reason for this I think is because being a really good Steady guy takes a lot of work and practice. It is clear to see that you have quite a passion for filmaking but I think you should consider getting more focused before buying a steady-cam. I think you will regret buying a bunch of different specialty job film equipment. Take some time and decide what job you really want to do and focus in on that area. You will be much more successful if you have a focused plan then by trying to do everything.
Some steady-cam guys may be able to add some insight further into this.
