I don't know that I'd call it "second generation". I went to Drexel University, which was the first college in the US to require incoming freshmen to purchase personal computers. This was in 1983, the year after I enrolled. They selected the Apple Macintosh, which had yet to be released, and freshman got the first batch of 128K Macs, with a Drexel Logo emblazoned on it to prevent them from selling them off to buyers 4 months before they were available on the open market. The 128K was replaced by "The 512" and then the MacPlus came out after that. As a Computer Science major a lot of my work was being taylored for the Mac, so I wound up buying one in '86, my Junior year (which is year 4 out of 5 since Drexel had a mandatory co-op program that had me spending 18 months in industry). I want to say it was close to $2500 for the computer and an external floppy drive (this with the Drexel student discount of 15% off retail).
The
wikipedia link is pretty thorough in explaining the timeline. The SE and Mac II came out after I graduated. They seem to be getting anywhere from $50-250 on eBay depending on features and extras. I'm thinking I might be able to get $150 if I waited long enough.
