you did a great job! as always, very informative and non-biased.
you could mark the lupine systems encoder as discontinued also just to be thorough 
Thanks, I may do that. For that matter, thanks for the help on the Lupine Encoder. Much of the trial data came from your posts.
When I say discontinued, I tend to mean - not available, you might find one on E-bay or the Buy/Sell/Trade forum here or someone may happen to run across one.
At the time I was writing the update, the Lupine Encoder was available, but I think it will rapidly fall into the category above.
It's probably something I should change. I'll fix it soon.
