My 2nd bike was a 92 Seca II. I had it til 97 when I got a Bandit 1200. The Seca was lots of fun, and also reasonable on trips - from San Jose I went to the Grand Canyon, Santa Barbara, Reno. I got a Corbin seat with more padding to help with legroom.
Definitely not super powerful, but light. And the lack of power is sort of fun because you can really ride the heck out of it, something that I can't really do with the Bandit and even less so with a 600cc sportbike.
The Seca build quality was very good, better than the Bandit. But after 9 years it's more related to how the bike was kept than anything else.
The miles are pretty low on this bike that you see, so you should probably check for things like old-fuel-clogged carbs, aged tires (possibly still has the originals, but that's too old), old brake fluid, etc. No coolant to worry about, that's a plus.
An SV is definitely better tech, but also will cost more, and I found them to be a little more cramped than the Seca. I'm 6'2" for reference.
Well whatever you get, it's all about the ride!
