Haha, I do remember seeing those Zemmixs growing up. (Never actually owned one though...
)
Anyway, I don't "collect" systems per se, so I buy systems that are practical. And buying either the Zemmix or a Vistar would now be for collecting rather than playing, as the alternatives to each are much more practical/functional.
Now, the Samsung Saturn, on the other hand, I'd pry put some money down on that one. It's the only Saturn system with a multi-voltage psu, which in my case, can come in quite handy.
