Hey Andy,
I purchased an Arriflex 16BL on Ebay just this July with a video tap and Tobin upgrade. I am pleased and excited about it. My advice? Go for it. I'm also looking into sound. Call the folks at Visual Products. I purchased a power cable and a small video monitor for the video tap from them. They'll answer all your questions and give you the attention you need no matter how big or small your purchase. They are a goldmine. Just saving up for support and sound. You can buy an analog recorder then digitalise it (you can do the same with the film and edit it on your computer.) No matter if I fall on my face with my first feature I own the equipment and can keep on filming. It's a very cost effective way. Read Robert Rodriguez's book "Rebel Without a Crew" and just DO IT.
Michael E.
