The market has changed a lot since I first started looking at it a few years ago when mocap rigs started at about $100,000. There are several systems out there now that start at about $10,000 with $15,000 being a good starting point for a complete SIMPLE hw/sw system. That's till too much for me. Luckily, I'm both a mathematician and a programmer, so I can build my own. I figured other mathematician programmers who were into 3D animation could do the same too, and I could share what I've learned with them (and learn more myself). My system is based on slightly older and more expensive technology. I just bought 4 camcorders for less than I paid for my first DV camcorder. The latest thing is using web cams which are much cheaper (like with Visual Marker). I'm sure you could do the same with older analog camcorders (with beta and Hi8 being preferred for their resolution). Regards, Michael
