We use a 3Doodler Pro+ at work, which I think might be the most expensive one out there? I've got to say, it really isn't any easier to use than the cheapest alternatives on the market... There's just a horrendous learning curve to these things in general, although if you think of it as any other art form then I guess it's probably comparable.
On ours, I do really appreciate the wide heat range, the ability to access the dual gear extruder during operation, and the swappable nozzles. What I don't appreciate is the ridiculous markup, the non-standard nozzle size, and them lying about only being able to use their special proprietary filament (it's just normal 2.85mm).
