Mr. Horst did not ask for advice wether to buy a single or a twin, but wether to buy a Seneca or an Aztec...
That's true, but I think he got some alternatives offered because it is so common for novices in GA to be pushed into the twin route.
When I was doing my PPL, everybody was telling me when I would be moving "up" to twins.
Moving "up" to twins seems to be often seen as some kind of macho thing to do, but is so expensive (relative to the return) that many of the people who do make the move are never seen flying again.
