The flash forge doesnt even sound half bad, even better that it has dual extrusion.
The build plate doesnt sound that much smaller then the ultimaker 2+.

I have to find a good side to side video of the flash forge vs the ultimaker.
Im aware that its not a fair comparison, since the ultimaker costs more then double, but I cant get a feel for the differences in the building volume.
Otherwise I would be hands down for the flash forge, sounds neat.
