plenty of industrial type deltas, some really big ones too.

But for a first printer I'd be inclined to go with a monoprice. pre-built, massive user base and the company is the worlds largest 3d printer seller (on numbers sold) for a good reason.

Once you've got imnto the whole art of 3d printing. Then it's time to start looking at kits and larger machines.

Never actually used an i3 clone - just can't think anything good can ever come of moving the whole bed back and forth like that. That said, they are really really popular - and dirt cheap., plus I prefer to print on the top edge of my machines capabilities, speedwise :-)
