To answer the first of your questions, since I have no experience (unfortunately) on the others, turbocharged Mac SE's (maybe not from that exact brand, but there are several different models including just sticking an SE/30 motherboard in a plain-jane SE do occasionally pop-up. That particular one I was not aware of, but from time to time, just quite rarely, someone does indeed put a turbocharged SE up for sale.
(I used to have a SE, but a networking experiment with a beige G3 desktop I had at the time corrupted the OS, and since I didn't have another working hard disk, I wound up having to part with it. Shame too, as it was working fine before I didn't listen to the signs that it wasn't working right (the networking experiments.)
The plain-Jane SE I had though was the most reliable and well-functioning compact Mac I ever had. And I liked it, although a 128k has stolen my heart now. Not working as well is it, but a charmer nonetheless is it...
Hope this helps and have a great day!
