A Solidoodle's consistency at printing is pretty good if there is never any user error. The Repetier software allows you full control of the printer, which is a good thing only sometimes. I've accidentally left my nozzle up to temperature resulting in a clog. I've run the printer too quickly, resulting in shifted layers on prints. Overall, it is actually much better to use than I expected. Once you figure out the machines little nuances, then it is a very consistent machine.
That being said, my school just got an Ultimaker 2...
Everything dealing with that machine puts my Solidoodle to shame. It DOES print right out of the box. The calibration is minimal and guided by the graphic OLED display. The whole machine was up and printing in less than 15 minutes. My Solidoodle took a few hours by comparison. Keep in mind however that my Solidoodle 3 was $799 and the Ultimaker 2 is around $2500. What you put into the machine is what you get out of it. Be that time or money, both can yield the same result.
