I just did extensive research, and not only is this a well-documented issue, but there is now a solution. The bad news is it's a complex electrical device that has to be built (well beyond my expertise), and no one seems to be selling one.
Here is the link.
At the bottom of that first post is a link to a very detailed PDF instruction for building an SAS Scaler.
If someone can build me one, I will pay. I salvaged my STi rack from the scrap dumpster, replaced the $5 pinion shaft seal (the one that always leaks), and put it in. Realistically, I saved hundreds of dollars, so I'm very willing to put some of that towards this device.
