If you have - as many companies do, a couple of miles of structured COAX in your walls - the cost of ripping out and upgrading just ONE run comforatbly exceeds 160 quid which will get you a half trained gibbon for a day.
Indeed. I thought I made that clear, however not strictly for long runs of inferior 75ohm cable. They would almost certainly work tho, as the cable is not part of an overall net - just working as a point to point link.
