I was considering purchasing their CubePro with the duel extruders but I got turned off by a couple of factors. For one they use proprietary cartridges that are literally double the cost of buying filament on spools. You're limited as to what they have available and although they advertise Nylon, it's still not available. It also doesn't have a heated bed, which to me is ludicrous for a printer that costs over $3500. On top of all that the software isn't very robust.
