Maruishi is still around - now known as Jamis. Very well respected marque, both past and present. I had a Maruishi Emporer and still remember the ride - smooth and buttery.

I believe these had Ishiwata EX or EXO, triple or quad butted cromoly.

For flipping, though, not sure how much more than $160 you'd get out of it. Because the marque is not that well known by the public, tends to fly under the radar. If it's your size, I'd buy it and keep it.
