if you're in the states go into a microcenter and buy a powerspec ultra - it's a creator pro for $999.

As for dual extrusion - I've got it on two machines - still haven't really got it working properly.

I can see it being useful - but it's not that simple to use - on replicator clone.

Other machines have different and far easier and more effective ways to implement it.


Good luck making money though - not easy.
