I would have to agree with the other replies on this thread. Printrbot is hands down one of the best printers for its price point. Also, an advantage to having some extra money left over after purchasing one means you can add on mods. I have a Printrbot Simple Metal and have been using it for about a year and have been loving it. There is a few things I have added onto my printer to increase quality and function.

Add-ons:
Raspberry Pi Model B+ paired with AstroPrint - Allows for wireless printing
E3D V6 hotend - Single greatest addition to my machine: increases quality, speed, and filament usage over the Ubis hotend that comes with the Printrbot Simple Metal
X-Axis Upgrade Heated Bed - Allows for an extra 4" of printing area plus a heated bed option (print volume: 10"x6"x6")

If you are interested in a Printrbot contact me (keith@eezitec.com) we have a wide range of 3D printers that we sell or if you want more information on my personal experience with Printrbots.

Hope this helps
