unit evaluation sugestions!

Hello everybody!
I’m eager to get some feed back on this Mocap package.
which is available from.
Arena Motion capture software
http://www.naturalpoint.com/optitrack/products/full-body-mocap.html
http://www.naturalpoint.com/optitrack/

It offers 6-8-12 4 mega pixel cameras,
with real-time data capture for at least 4999.

However looking at it in more depth,
the 4 mega pixel cameras are 529 each.
Whereby a Sony HD camera is only 300+.

From what I can gather, Realviz claims you only need two or three of these HD cameras,
to get enough parallax to do your Mocap data.

So what I’d really kinda like to know is, is it over priced,
would I simply be paying just for the cables and the single-user controls?

Any ideas are welcome, Thanks!
