MakerGeeks Makes their own filament in the USA and ships direct, so you know who to credit/blame. I am extremely favorably impressed by their Raptor PLA series. The Raptor PLA carries a premium price, but gives excellent results. I love how it prints, and it's much stronger than standard PLA after you heat treat / anneal it. I've also used their standard Maker PLA, Crystal PLA, and ABS filament. The Maker PLA works great, the Crystal PLA turns some really beautiful pieces, and ABS is well, ABS. Iv'e not tried their PETG series.
