I have had great results with Sunlu. I especially like their red silk pla. I found their masterspool system and was impressed that comes with a spool. The PLA Masterspool is not as great of a deal at $45, but the PETG is a fantastic deal at $43. The PETG Mastspool system comes Red and Black, Black and White, and Black and Blue. I have seen some complaints, btu I have none. Near perfect results so far. Anyone else use it?
