Wanted to do an update, but me and Courtney have both been sick. Will post more at a better time.
But I do have good news. The Praxis 48 I had given up for dead suddenly started working again. The E key had been unresponsive, but just like Vern said, it freed up once I worked it enough. Now the only problem is that several keys will keep striking if I hold them down. I could barely get through a short letter on the darn thing, and it was a rather difficult machine to type with. May just be part of learning the touch. The space bar was the most frustrating of all. I think it's way too easy to put multiple spaces between words if your touch is on the heavy side.
All for now.
Power to the pen!
