MAKE also tested the pp3dp UP, and IMHO it's the overall easiest regarding hard- and software, great support structure generation, and quality is good, too!

They had the PDF issue and review online for free for a while, not anymore it seems. Perhaps you can find the review somewhere.

I have tried Printrbot LC, Reprap Mendel and the UP, all Reprap based devices will give you more freedom but the software is not as smooth, and thus results are not as constant - the slicing is just as important as the printer's hardware reliability.

I had no clue about 3D printers when I bought it, and it worked from the start, even with complex and tiny models.
