Phil, you are getting good advice here. For reviews, rather check 3dhubs.com as that is a community of makers and professionals.
For Plug n play, the Robox is a very good machine. I have seen it around, it is a popular machine. Because it doesn't use a complicated Bowden tube assembly you are likely to have little extrusion issues although it is not an optimal extruder. Read up on it on the specific 3D printer pages of this forum.
