Does anyone know how economical it is using a filament extruder?

Hello all, I’ve been burning through a lot of filament due to the recent craze in fidget spinners as well as due to a lot of personal projects. I was wondering if there was anyone out there who has one of those filament extruders, and if so on average how much do you save as opposed to just buying filament from a site such as Amazon. Also, how practical is it? http://ift.tt/2rT1YZv

Just won Robo R1 plus. Keep or Sell+upgrade?

I’ve never 3d printed before, but used to follow the reprap community very closely. I am really excited to jump in, but I don’t want to start going on the Robo if I could jump into something better for little more investment and I’m sure I can sell it for more if I don’t open the box.UPDATEThanks for the feedback, between this and facebook I have decided to keep it. Can’t wait to start printing! http://ift.tt/2rpnfZb
