Roger, I think the point Ned was making is that it has a somewhat limited capacity, but the price is low enough that it's affordable for someone who's just starting to put a shop together. You're right about the size limiting the thickness of lumber you can cut, but often there are power issues with smaller saws, too. Smaller saws typically don't have a lot of horses under the hood (which is fine for the thinner stock they are use on), but by the time you get into a 6" saw like yours, the motor horsepower can be increased quite a bit.
Ryan, I know of several guys who've bought these to use as a dedicated scrolling saw. If I had the room, I'd be tempted myself. The little Rikon has a good reputation. (So do their bigger models.) And this is indeed a good price.
