No thanks. Just like anything else, I'd get tired of them eventually. Beside, most of those SOS's are older than I am, so I'm by no means the expert. It's just that I have worked on a few in the past.
I'm more into the new powershifts. Electronically controlled versions. Sweet is the only word you can use to compare them to the SOS. However, I still maintain that the SOS was a decent trans for its time.
