Best Of Both Worlds? HDSDI

For analog customers before they jump to IP all together, we are considering the HD-SDI system even though has never been really pick up, but we are beginning to think as the HDSDI DVR prices drop this may be a feasible solution for the price sensitive customers here.
Questions:
1. How to determine IF the existing coaxial cable at the customer's site is still in good enough condition to be use for the HD-SDI? I only read that the coax is suppose to read 75 ohm for 100 meter long cable, but in reality we never know how long the installed cables are so how will the length affect the reading and is there some mathematical formulas for calculating that?
2. What kind of device to read this different length and what is the maximum acceptable resistance in ohms for the coax cable?
