Edd, As you mentioned the load is so small. I believe that it is insignificant to justify the cost and time of adding even just a simple switch. That being said, like nearly all electronic devices, the Link2000 has a power supply (+ and -). Put a switch in line with the + and presto you have a means for turning it off. The advantage of leaving it on is that it will continue to monitor current draw from things like the bilge pump, led anchor light, radio memory, and cigarette lighter accessories. Individually these are also insignificant but overtime they may accumulate a surprisingly large number of amp hours which would go unmonitored without the Link 2000 (or other battery monitor being on. Even the draw of the Link 2000 should be being monitored assuming it is on and wired correctly.
For anybody looking for a cheap solution check out the DROK products on Amazon. I've been extremely impressed with the price, quality, and functionality. For loads less than 20 amps they have a modle with an integrated shunt. For greater than 20 amps you'll need to make sure to plan for a shunt (always on the ground).
