I am so much more interested these days in the HMC 150 than the 170.. based in large part on the price and what that difference will allow me to by in addition. I just can't wait to get my hands on one.. at this price... I'm willing to take another chance.
I would consider the HMC150 for the extra bit of resolution, just at the end of the day I see a lot more of the client base, or production base, requestin' the HPX170 knowing that it's the same P2 workflow they trust with added benefits on set.
Cameras, not a fun thing to deal with.
