Continuing on topic, a run from mixer to video source is around 100í.
I see Roland VC-1-SH SDI to HDMI for sale in the marketplace. Would SDI be a good choice for the 100í run? I am guessing that 75 ohm cable is what you use?
For converting the video source hdmi to sdi, would I need the Roland version, or will other units work. Given that I donít want to spend $500 which is about what the  Roland hdmi to sdi costs, what would be a good value for this?
On benny for me would be reducing the number of cables to run to the video source (now I have a powered 120í hdmi cable to the projector area and a pair of XLR cables to the mixer.

I like SDI for longer video runs.  Sdi to hdmi converters can, at times be problematic, as sdi generally supports a range of resolution and scan rate combos that the TVs on the other side of the converter donít support.   Depending on your source this may or may not be an issue for you. If you are starting hdmi, convert to sdi for the run and back to hdmi, then it almost always works...

Regardless, I like the cheap sdi converters that monoprice sells.  They generally work in the applications I use them in, but plenty of people have also had bad experiences where they donít work - most often I think this is due to an incomplete understanding of 3G sdi level A and level B.   Many of these cheaper converters canít handle level B correctly in my experience and see it as a 1080i stream....
