After some measuring my general run of thumb is "Anything you leave plugged in and running 24x7 will cost you triple digits of dollars (at least) over a year
Well, that's a lot of "anything." There are 8760 hours in a year, so a 1 kW load will consume 8760 kWH per year. We pay about $0.08 per kWH here, so a 1 kW load running 24/7 costs just over $700/year (= $0.70 per W per year). That puts the "three digit" point ($100/yr) at ~143 W. I leave a number of LED bulbs running 24/7, which cost ~$2.80/yr for 4 W, ~$5.60/yr for 8 W, and ~$8.40/yr for 12 W. Even a new 50" flat-screen television (119 W) would only cost ~$83/yr if left on 24/7, and my quad-core workstation with its huge display would cost only ~$250.
In another post you mentioned $0.21/kWH (you must be in California?), so adjust all of these by a factor of 2.625 for your location -- but I think the service rates in most of the US are closer to ours than to yours).
