Wow, I have tried maker geeks and have had so many problems with it. The plastic is really cheap and clogs easy, and I found that my extruder's bolt could not grab the filament for anything after the first 1/4 of my first spool. When I contacted support about the filament appearing to have quality control issues, they sent me another spool for free, however it had the same issue.
I've heard a lot of good things about Ultimachine, but I haven't gotten around to buying a new spool yet. Also, if you're looking for a US distributer of colorfabb, I know matterhackers.com caries it.
